Abstract:
We describe a neural network able to rapidly establish correspondence between neural feature layers. Each of the network's two layers consists of interconnected cortical columns, and each column consists of inhibitorily coupled subpopulations of excitatory neurons. The dynamics of the system builds on a dynamic model of a single column, which is consistent with recent experimental findings. The network realizes dynamic links between its layers with the help of specialized columns that evaluate similarities between the activity distributions of local feature cell populations, are subject to a topology constraint, and can gate the transfer of feature information between the neural layers. The system can robustly be applied to natural images, and correspondences are found in time intervals estimated to be smaller than 100 ms in physiological terms.

Abstract:
In this paper, a hybrid scheme is proposed to find the reliable point-correspondences between two images, which combines the distribution of invariant spatial feature description and frequency domain alignment based on two-stage coarse to fine refinement strategy. Firstly, the source and the target images are both down-sampled by the image pyramid algorithm in a hierarchical multi-scale way. The Fourier-Mellin transform is applied to obtain the transformation parameters at the coarse level between the image pairs; then, the parameters can serve as the initial coarse guess, to guide the following feature matching step at the original scale, where the correspondences are restricted in a search window determined by the deformation between the reference image and the current image; Finally, a novel matching strategy is developed to reject the false matches by validating geometrical relationships between candidate matching points. By doing so, the alignment parameters are refined, which is more accurate and more flexible than a robust fitting technique. This in return can provide a more accurate result for feature correspondence. Experiments on real and synthetic image-pairs show that our approach provides satisfactory feature matching performance.

Abstract:
Points matching is a key technology in close-range photogrammetry. The epipolar line constraint that confines the research area from two dimensions to one dimension, can improve the efficiency of matching process. In the paper, coded targets are applied to get a set of accurate correspondences of points between images, and then the correspondence set is used for calculating fundamental matrices by normalized 8-points algorithm that can be implemented quickly and simply. Because of the ambiguities, a completely accurate correspondence set will not be gained only by epipolar line constraint, and other technologies should be combined with epipolar line constraint. Three views are used to decrease ambiguities, and a method of dynamic threshold is presented to reject wrong correspondences. A proper threshold is calculated, and those correspondences whose corresponding distance is larger than the dynamic threshold, are considered as wrong matching points. Many experiments show that the correct rate of matching is about 99.98%, which means an automatic, efficient, accurate matching process can be implemented by the methods in this paper.

Abstract:
The importance of finding correct correspondences between two images is the major aspect in problems such as appearance-based robot localization and content-based image retrieval. Local feature matching has become a commonly used method to compare images, despite being highly probable that at least some of the matchings/correspondences it detects are incorrect. In this paper, we describe a novel approach to local feature matching, named Feature Group Matching (FGM), to select stable features and obtain a more reliable similarity value between two images. The proposed technique is demonstrated to be translational, rotational and scaling invariant. Experimental evaluation was performed on large and heterogeneous datasets of images using SIFT and SURF, the actual state-of-the-art feature extractors. Results show that FGM avoids almost 95% of incorrect matchings, reduces the visual aliasing (number of images considered similar) and increases both robotic localization and image retrieval accuracy on the average of 13%.

Abstract:
To solve the dense matching problem for stereoscopic satellite images, a hybrid matching scheme integrating multiple methods is proposed. This scheme utilizes two types of matching element including grid points and edge points. First the geometrically constrained cross-correlation (GC3) method is used to extract matching grids. While in less textured regions using GC3 cannot get sufficient matching grids, so the local affine transformation is used to establish the region correspondence, and more matching grids can be generated. Edges are extracted by Canny operator and approximated with a series of straight edge segments using a polygon approximation. Based on these approximated edges, edge correspondences between image pairs are established using GC3. This scheme fuses the region based and the feature based matching methods. It has been tested with real satellite images and the results demonstrate its accuracy and efficiency.

Abstract:
Co-registering the Sentinel-1 Synthetic Aperture Radar (SAR) and Sentinel-2 optical data of the European Space Agency (ESA) is of great importance for many remote sensing applications. However, we find that there are evident misregistration shifts between the Sentinel-1 SAR and Sentinel-2 optical images that are directly downloaded from the official website. To address that, this paper presents a fast and effective registration method for the two types of images. In the proposed method, a block-based scheme is first designed to extract evenly distributed interest points. Then, the correspondences are detected by using the similarity of structural features between the SAR and optical images, where the three-dimensional (3D) phase correlation (PC) is used as the similarity measure for accelerating image matching. Lastly, the obtained correspondences are employed to measure the misregistration shifts between the images. Moreover, to eliminate the misregistration, we use some representative geometric transformation models such as polynomial models, projective models, and rational function models for the co-registration of the two types of images, and we compare and analyze their registration accuracy under different numbers of control points and different terrains. Six pairs of the Sentinel-1 SAR L1 and Sentinel-2 optical L1C images covering three different terrains are tested in our experiments. Experimental results show that the proposed method can achieve precise correspondences between the images, and the third-order polynomial achieves the most satisfactory registration results. Its registration accuracy of the flat areas is less than 1.0 10 m pixel, that of the hilly areas is about 1.5 10 m pixels, and that of the mountainous areas is between 1.7 and 2.3 10 m pixels, which significantly improves the co-registration accuracy of the Sentinel-1 SAR and Sentinel-2 optical images.

Abstract:
This paper presents a spectral method to matching a pair of feature sets based on isometric projection of matrix. In the proposed method, a graph is constructed to model the structure relationships between features. Then the correspondence is found by minimizing the inner product between two isometric projections of the weighted adjacency matrix of graph. Finally, transformation between the two feature sets is estimated according to correct correspondences. The performance of the proposed approach is better than the state-of-the-art method in terms of correct ratio under position perturbation and computation time. Experiments on a number of simulated data, synthetic and real-world images show the validity of the proposed algorithm.

Abstract:
Stereo matching is widely used in three-dimensional (3D) reconstruction, stereo machine vision and digital image correlation. The aim of stereo matching process is to solve the well-known correspondence problem, which tries to match points or features from one image with the same points or features in another image from the same 3D scene. There are two basic ways, correlation-based and feature-based, are used to find the correspondences between two images. The correlation-based way is to determine if one location in one image looks/seems like another in another image, and the feature-based way to find if a subset of features in one image is similar in the another image. In stereo matching, a simple algorithm is to compare small patches between two rectified images by correlation search. For the pair images acquired from two cameras inevitably exists some rotation transformation, the algorithm first runs a preprocessing step to rectify the images with the epipolar rectification to simplify the problem of finding matching points between images. The epipolar rectification is to determine a transformation of each image plane such that pairs of conjugate epipolar lines become collinear and parallel to one of the image axes. It will lead the loss of gray information of images. The effect is dependent on the amount of angle. When the angle is big enough, the correlation search may yield error results because of retrograded correlation effect. In order to solve the problem, the paper presents an improved stereo matching algorithm with differential evolution to solve the correspondence problem. Our method doesn’t need to runs the preprocessing step to rectify the images with the epipolar rectification. It uses a differential evolution algorithm to minimize the correlation function which contains the angle information after acquiring the epipoar geometry constraint of two image pairs. Then it utilizes a flood-fill algorithm to search correspondence sub-region in the area around the epipolar line. The flood-fill algorithm can overcome the problem of the traditional row-column scanning search method, which will encounter boundary barrier where exists concave polygons or cavities. The Experimental results show that the proposed method can be easily implemented in stereo matching without loss of information of image features with large rotation angle transformation. In the paper, we will introduce the stereo matching principle and its algorithms, including the differential evolution algorithm for finding the correspondences with large rotation transformation between stereo image pairs and the flood-fill traversal strategy for matching large area with complex concave polygons or cavities. In the end of the paper, some experimental results will be given to illustrate the method effectiveness. Keywords: digital image correlation, stereo matching algorithm, epipolar geometry, flood fill algorithm, differential evolution, rotation angle

Abstract:
Conventional neural networks try to solve the problem of object recognition in a single step by building a stimulus — response system that codes its result as cell activities. We take a different approach assuming that recognition is an active process with temporal dynamics and results in an ordered state. We present a structure of neuronal layers, interconnected by dynamic links (von der Malsburg, 1985 Berichte der Bunsengesellschaft für Physikalische Chemie89 703 – 710) that solves the correspondence problem between two images and thus constitutes an important building block for a model of recognition. Images as well as stored models are represented as Gabor pyramids. This allows the dynamics to proceed from coarse to fine scale and reduces the sequential processing time inherent in the concept. Invariance under background changes is also made possible. On the lowest frequency level, a single blob of activity moves across the image and model layer, respectively. Dynamic links between these layers are initialised to the (highly ambiguous) feature similarities. Links grow or decline according to a combination of feature similarity and correlated activation. This enforces correct neighbourhood relationships in addition to feature similarity. On the higher levels the established correspondences are refined by several blobs in parallel. We present an improved version of the dynamical system proposed by Würtz [1995 Multilayer Dynamic Link Networks for Establishing Image Point Correspondences and Visual Object Recognition (Thun, Frankfurt a.M.: Harri Deutsch)] and show, with examples of human faces, that it evolves from an unordered link distribution to any ordered state where only corresponding point pairs are connected by strong links. Correspondences between sample points are population-coded by a set of neighbouring links.

Abstract:
Detection of objects based on color is not commonly used method of computer vision. There are many methods thats deals with the detection of significant points, but the color information has been omitted. The goal of this thesis is to design method of the detection significant color image areas and these areas match up with areas detected in another image. I analyzed features of detectors required to identify the reciprocal correspondence of images, defined the color significance concept, described basic color models and their properties, and a design of statistically compiled data - based method was described. Algorithms for the detection of color use color models RGB and HSV. Correspondence of areas detected in different images is performedy Kohonen neural network. The first input vector can teach Kohonen neural network and the second vector is classified by this network. To remove erroneous classifications RANSAC method is used. As a result, the method can be used for basic and rapid determination of correspondence between images, or to speed up commonly used methods for detection of significant points. At the end of the thesis are presented programs, showing functionality and options of design methods. The designed algorithms have been developed in MATLAB.

Abstract:
Doctor of Philosophy(PhD)<br>This thesis is concerned with the theoretical and practical development of a surface-based mapping algorithm for reliable and robust localization and mapping in prior unknown and unstructured environments. A surface-based map consists of a set of compressed surfaces, processed and represented without geometrical modelling. Each surface in the surface-based map represents an object in the environment. The ability to represent the exact shapes of objects via individual surfaces during the mapping process makes the surface-based mapping algorithm valuable in a number of navigation applications, such as mapping of prior unknown indoor and outdoor unstructured environments, target tracking, path planning and collision avoidance. The ability to unify representations of the same object taken from different viewpoints into a single surface makes the algorithm capable of working in multi-robot mapping applications. A surface-based map of the environment is build incrementally by acquiring the 3D range image of the scene, extracting the objects' surfaces from the 3D range image, aligning the set of extracted surfaces relative to the map and unifying the aligned set of surfaces with surfaces in the map. In the surface unification process the surfaces representing the same object are unified to make a single surface. The thesis introduces the following new methods which are used in the surface-based mapping algorithm: the extraction of surfaces from 3D range images based on a scanned surface continuity check; homogenization of the representation of the non-homogenously sampled surfaces; the alignment of the surface set relative to a large set of surfaces based on surface-based alignment algorithm; evaluating the correspondence between two surfaces based on the overlap area between surfaces; unification of the two surfaces belonging to the same object; and surface unification for a large set of surfaces. The theoretical contributions of this thesis are demonstrated with a series of practical implementations in different outdoor environments.

This thesis illustrates a general sense of national identity within the Taiwanese people brought on by the Kuomintang (KMT) and existing throughout the KMT's reign over the island, and contrasts this with the new identity that came to exist in the post-KMT period. Comparisons are centered around two works of literature: Sayonara, Zaijian!, written in 1979 by Chunming Huang, and My Diary of Japanomania, written in 1999 by Hari Xingzi. Louis Althusser's view of history-based on structural materialism, complexity and overdetermination---will be employed to discuss and explain the contrast between Sayonara, Zaijian! and My Diary of Japanomania in order to discover how national subject is formed and how it interacts within ideology.

Abstract:
碩士<br>國立臺灣大學<br>資訊工程學研究所<br>95<br>In this work, a framework relying on image-based rendering is presented for synthesizing intermediate views in the forward transition of two uncalibrated images without using explicit geometry information. First, the source and destination images are partitioned into regions. Each region is a presentation of the scene surface which can be approximated by a plane. To generate the intermediate views during the transition, each region is morphed according to its warping function individually. The warping function adopted here is derived from homography. Homography is estimated by using the corresponding feature points found by SIFT in the source and destination images. The morphed regions are combined to generate the intermediate image at a specific moment. Then the sequence of synthesized intermediate views can be played successively to produce smooth view hopping. Each morphed image can be further improved by zoom-blurring. Taking advantage of visual effect by zoom-blurring, the whole sequence of intermediate views would be more absorbing. We also introduce painting styles provided by non-photorealistic rendering, so that view hopping with artistic styles is also available in our framework.

Abstract:
碩士<br>國立交通大學<br>應用藝術所<br>88<br>Abstract Walter Benjamin has suggested that once we try to evolve the skill of the art, we can make the art progress. Plenty of artists try to use newspaper,movies,radio as well as photography froquentlly as kinds of new art production skill. Accordingly, an artist would not only be care about the goal of the art but also the tool of the art croation. They have been making their effort to understand how to construct art form technically. Computer images are basically built up by the novel science and technology formally. It was operated coordinately with the modernism as well as the mixing of clloage technique. Could it happen that to construct an art by the use of computer media would replace the impression of the one construct by the traditional artistic construction media? Computer artist uses the computer software constructed by modern science and technology to be engaged in the art composition. Then, the command-oriented computer software should be related to the form of the depth perception of the modern computer art. In that case, the commands would affect the art form and the style. They might guide the users to follow the convention to build up their artistic creation. The design of the command may influent the art form. It causes the art form to be the relacted result of the command. As a result of those comments, the study infer that the commands of the image software like Copy, Cut, Paste, Transform, Scale, Filter, and Image may cause the style or the form of the artistic production with the convention or customary practice. Accordingly, the study impliment three experiments to investigate the relationship between computer commands and the depth perception. Experiment 1: The purpose of this experiment was to inspect the identification of the commands which were used. Experiment 2:To analyse the general habits and characteristics of those computer artists in using those commands in form and evaluated the commands which were used by the used computer artist selected from SIGGRAPH97-98. Experiment 3:The study obtain the tendency of overall depth impression from the 35 SIGGRAPH97-98 computer image productions.The study investigated the most effective one among the models of depth perception on the computer images .The relationships between the commands and the depth perception were alse examined. Accroding to the experiment, command and the depth perception are related. Computer artist tend to use simple command to create art work .There is an obvious relationship among Perspective, Relative Size,Texture Gradints, and Atmospheric perspective .Using the Scale and Curves command affect computer image’s depth perception.Scale command causes the Perspective and Reative Size effects by changing the size.Curves command causes Color and Texture Gradints effects by changing the color.

Abstract:
In December 1945 the "L'Approdo" transmissions were launched at the RAI headquarters in Florence. The radio programme, one of the most important in Italy at the time, went on the air up to 1977, being accompanied from 1952 by a magazine and from 1963 to 1972 by a television programme. The three parallel cultural "enterprises" boasted an impressive number of important collaborators, gravitating around the decisive figure of Carlo Betocchi as leader and organiser. Nevertheless, despite its significance, even the adventure of "L'Approdo" was destined to die. When the transmissions and the publication of the magazine ceased, an entire cultural élite had to come to terms not only with the objective difficulties, but with a crisis of trust and of commitment in the face of what were now irreversible changes in the country. Yet – precisely because "L'Approdo" had battled for an approach that was destined to become minority with the triumph of the new media society – the retrieval of its history and the reconstruction through voices, pages and images of one of the first examples of encounter and mediation between culture and communication appears particularly significant. The methods and the emphatic planning of the entire experience emerge clearly from the first issue of the magazine, produced here in anastatic reprint, and above all from the enclosed CD-Rom which proposes, along with the tables of contents of "L'Approdo", the files and records of the entire correspondence (over 20,000 unpublished pieces) and details of the surviving scripts of the transmissions… In short, we finally have at our disposal material that enables us to reconstruct – through the traces of a programme and a magazine and of the intellectuals who collaborated on them – thirty years of culture and utopia, of compromise and enthusiasm, clustered around the birth, growth and death of an articulated project of "cultural policy".

Abstract:
Many researchers argue or accept that crossmodal matchings or mappings, such as those that exist between pitch and brightness, and canonical cases of conscious synaesthesia lie at the two ends of a continuum. This chapter raises problems for this continuity claim regarding (i) the distribution of conscious manifestations, and (ii) the dimensions along which this continuum should be organized. It reviews possible candidate dimensions, including the degree of vividness, frequency, specificity of the conscious manifestation, and control over its content, and shows that evidence of the expected distribution is absent for all of these continua. Although a crude distinction between conscious and non-conscious might not be sufficient to separate synaesthesia from crossmodal correspondences, the conscious manifestations that characterize synaesthesia cannot be reconciled with other occasional occurrences of mental imagery documented for crossmodal correspondences.

Full text
Abstract:
While denotative images celebrating aspects of Nerva’s policy have attracted most scholarly study, their importance is overemphasized since the most common images on Nerva’s coinage are personifications of imperial ideals such as Libertas, Aequitas, and Fortuna. Many scholars have dismissed such images as generic and repetitive. There is a strong correspondence between the personifications and contemporary writers who ascribe the same qualities to Nerva. These coins thus visualize the written and spoken praise directed at Nerva by contemporaries. The frequency and widespread distribution of these images obviates the interpretation that the images were directed exclusively at the Senate. The generality of personifications allowed viewers to bring their own interpretation to them. Libertas, for example, is one of the most common images on Nerva’s coins, and could be understood in different ways by viewers. In addition to freedom from tyranny (a senator’s understanding), Libertas also could evoke freedom from taxation.

Abstract:
The strong correspondence between laudatory rhetoric in poetry and panegyric and the images that appear on Nerva’s coins allows a reinvestigation of the age-old debate regarding the agency behind the creation of Roman imperial coin iconography. The evidence available, at least in Nerva’s reign, suggests that the emperor was not the agent; instead, a prominent individual in charge of the mint was responsible for the selection of the imagery. By attending to Trajanic records, it appears that such individuals were very close to the emperor and known to him. This suggests that prominent equestrians in charge of the mint thus were part of the emperor’s inner circle and walked in the same social circles as the people who inked praise directed at the emperor: Martial, Frontinus, Tacitus, and Pliny. These prominent equestrians were thus in a position to visualize the rhetoric used to praise the emperor.

Abstract:
This chapter examines how enemy images are produced and reproduced in relations between two enemies. It identifies four drivers of security competition that block the development of trust. These are: (1) the security dilemma; (2) the problem of offence–defence differentiation; (3) peaceful/defensive self-images; (4) ideological fundamentalism; and (5) uncertainty about future intentions. Using examples such as the military stand-off on the Korean peninsula and the Libyan dismantlement of weapons of mass destruction, the chapter shows how hard it is for face-to-face diplomacy to change enemy images. It also examines the problem of ‘future uncertainty’—the problem of what happens if successor leaders do not share the trust of their predecessors and have malign intent.

Abstract:
Travelling images critically examines the migrations and transformations of images as they travel between different image communities. It consists of four case studies covering the period 1870–2010 and includes photocollages, window displays, fashion imagery and contemporary art projects. Through these four close-ups it seeks to reveal the mechanisms, nature and character of these migration processes, and the agents behind them, as well as the sites where they have taken place. The overall aim of this book is thus to understand the mechanisms of interfacing events in the borderlands of the art world. Two key arguments are developed in the book, reflected by its title Travelling images. First, the notion of travel and focus on movements and transformations signal an emphasis on the similarities between cultural artefacts and living beings. The book considers ‘the social biography’ and ‘ecology’ of images, but also, on a more profound level, the biography and ecology of the notion of art. In doing so, it merges perspectives from art history and image studies with media studies. Consequently, it combines a focus on the individual case, typical for art history and material culture studies with a focus on processes and systems, on continuities and ruptures, and alternate histories inspired by media archaeology and cultural historical media studies. Second, the central concept of image is in this book used to designate both visual conventions, patterns or contents and tangible visual images. Thus it simultaneously consider of content and materiality.

Abstract:
Descartes’s Fictions traces common movements in early modern philosophy and literary method. This volume reassesses the significance of Descartes’s writing by bringing his philosophical output into contact with the literary treatises, exempla, and debates of his age. Arguing that humanist theorizing about the art of poetry represents a vital intellectual context for Descartes’s work, the volume offers readings of the controversies to which this poetic theory gives rise, with particular reference to the genre of tragicomedy, the question of verisimilitude, and the figures of Guez de Balzac and Pierre Corneille. Drawing on what Descartes says about, and to, his many contemporaries and correspondents embedded in the early modern republic of letters, this volume shows that poetics provides a repository of themes and images to which he returns repeatedly: fortune, method, error, providence, passion, and imagination, amongst others. Like the poets and theorists of the early modern period, Descartes is also drawn to the forms of attention that people may bring to his work. This interest finds expression in the mature Cartesian metaphysics of the Meditations, as well as, later, in the moral philosophy of his correspondence with Elisabeth of Bohemia or the Passions of the Soul. Some of the tropes of modern secondary criticism—a comparison of Descartes and Corneille, or the portrayal of Descartes as a ‘tragic’ figure—are also re-evaluated. This volume thus bridges the gap between Cartesian criticism and late-humanist literary culture in France.

Abstract:
The chapter discusses two modes of combining music and moving images that developed in modernism. The first mode, which the author termsgeneration, relates to a type of animated narrative film in which the music precedes the visual sequence which generates the will or thought (modality) that gives rise to the narrative action. “The Sorcerer’s Apprentice,” from the Disney filmFantasia, is examined as an example. In the second mode,suspension, the picture appears as if preceding the music, even if the creative order was different, or the work does not have an actual visual manifestation. The visual sequence, which appears as if deriving from the composer’s inner world, is characterized by minute occurrences, wishing to arouse as an atmosphere or “third consciousness.” The movement “Colors” from Schoenberg’sFive Pieces for an Orchestra, opus 16, is examined as an example alongside examples from film music.

Full text
Abstract:
The shifting image of the Hasmoneans in the eyes of their contemporaries and later generations is a compelling issue in the history of the Maccabean revolt and the Hasmonean commonwealth. Based on a series of six Jewish folktales from the Second Temple-period that describe the Hasmonean dynasty and its history from its legendary founders through achievement of full sovereignty to downfall, the present volume examines the Hasmoneans through the lens of reception history. On the one hand, these brief, colorful legends are embedded in the narrative of the historian of the age, Flavius Josephus On the other hand, they are scattered throughout the extensive halakhic-exegetical compositions known as rabbinic literature, redacted and compiled centuries later. Each set of parallel stories is examined for the motivation underlying its creation, its original message, language, and historical context. This analysis is followed by exploration of the nature of the relationship between the Josephan and the rabbinic versions, in an attempt to reconstruct the adaptation of the putative original traditions in the two corpora, and to decipher the disparities, different emphases, reworking, and unique orientations typical of each. These adaptations reflect the reception of the pristine tales and thus disclose the shifting images of the Hasmoneans in later generations and within distinct contexts. The compilation and characterization of sources which were preserved by means of two such different conduits of transmission brings us closer to reconstruction of a lost literary continent, a hidden Jewish “Atlantis” of early pseudo-historical legends and facilitates examination of the relationship between the substantially different libraries and worlds of Josephus and rabbinic literature.

Abstract:
AbstractThe signal acquired in sodium (23Na) MR imaging is proportional to the concentration of sodium in a voxel, and it is possible to convert between the two using external calibration phantoms. Postprocessing, and subsequent analysis, of sodium renal images is a simple task that can be performed with readily available software. Here we describe the process of conversion between sodium signal and concentration, estimation of the corticomedullary sodium gradient and the procedure used for quadrupolar relaxation analysis.This chapter is based upon work from the COST Action PARENCHIMA, a community-driven network funded by the European Cooperation in Science and Technology (COST) program of the European Union, which aims to improve the reproducibility and standardization of renal MRI biomarkers. This analysis protocol chapter is complemented by two separate chapters describing the basic concept and experimental procedure.

Abstract:
Seeking reliable correspondences between two feature sets is a fundamental and important task in computer vision. This paper attempts to remove mismatches from given putative image feature correspondences. To achieve the goal, an efficient approach, termed as locality preserving matching (LPM), is designed, the principle of which is to maintain the local neighborhood structures of those potential true matches. We formulate the problem into a mathematical model, and derive a closed-form solution with linearithmic time and linear space complexities. More specifically, our method can accomplish the mismatch removal from thousands of putative correspondences in only a few milliseconds. Experiments on various real image pairs for general feature matching, as well as for visual homing and image retrieval demonstrate the generality of our method for handling different types of image deformations, and it is more than two orders of magnitude faster than state-of-the-art methods in the same range of or better accuracy.

Abstract:
The paper describes a comprehensive approach to first reconstruct and then visualize three-dimensional image models created from a pair of two-dimensional digital color images. The method integrates an interactive output data manipulation capability of JView, a Java based API (Application Programming Interface) engineered by US Air Force (AFRL/IFSB) with newly developed more accurate procedure of recreating texture mapped 3D-models using a stereo triangulation technique. Though several procedures have been proposed in literature on how to generate 3D models from 2D stereo pairs by recovering the image depth, they are limited in predicting an accurate pixel matching between image correspondences. Furthermore, the majority of papers lack depicting the reconstructed 3D-image geometry to show how well their adopted techniques have been able to recover the scene depth at every pixel. We have employed a region-based block matching methodology for color image analysis. The reconstructed 3D image models can be viewed and maneuvered on a computer screen by moving up and down, rotating around, and zooming in and out with the help of mouse buttons. This interactive viewing capability is an aid to the visualization process and facilitates algorithm designers to test step-by-step their codes and make appropriate judgments as to the accuracy of the underlining reconstruction techniques (sort of a visual debugger). Example presented shows detailed disparity map and reconstructed geometries.

Abstract:
We address the challenging issue of deformable registration that robustly and efficiently builds dense correspondences between images. Traditional approaches upon iterative energy optimization typically invoke expensive computational load. Recent learning-based methods are able to efficiently predict deformation maps by incorporating learnable deep networks. Unfortunately, these deep networks are designated to learn deterministic features for classification tasks, which are not necessarily optimal for registration. In this paper, we propose a novel bi-level optimization model that enables jointly learning deformation maps and features for image registration. The bi-level model takes the energy for deformation computation as the upper-level optimization while formulates the maximum \emph{a posterior} (MAP) for features as the lower-level optimization. Further, we design learnable deep networks to simultaneously optimize the cooperative bi-level model, yielding robust and efficient registration. These deep networks derived from our bi-level optimization constitute an unsupervised end-to-end framework for learning both features and deformations. Extensive experiments of image-to-atlas and image-to-image deformable registration on 3D brain MR datasets demonstrate that we achieve state-of-the-art performance in terms of accuracy, efficiency, and robustness.

Abstract:
Stereo images are images formed from two or more sources that capture the same scene so that it is possible to infer the depth of the scene under analysis. The use of convolutional neural networks to compute these images has been shown to be a viable alternative due to its speed in finding the correspondence between the images. This raises questions related to the influence of structural parameters, such as size of kernel, stride and pooling policy on the performance of the neural network. To this end, this work sought to reproduce an article that deals with the topic and to explore the influence of the parameters mentioned above in function of the results of error rate and losses of the neural model. The results obtained reveal improvements. The influence of the parameters on the training time of the models was also notable, even using the GPU, the temporal difference in the training period between the maximum and minimum limits reached a ratio of six times.

Full text
Abstract:
Quantitative measurements of wall thickness in human abdominal aortic aneurysms (AAAs) may provide useful information to predict rupture risk. Our procedure for estimating wall thickness in AAAs includes medical image segmentation and wall thickness detection. Image segmentation requires identifying and segmenting the luminal and outer wall boundaries of the blood vessels and wall thickness can be calculated by using intensity histograms and neural networks. The goal of this study is to develop an image-based, semi-automated method to trace the contours of the vessel wall and measure the wall thickness of the abdominal aorta from in-vivo, contrast-enhanced, CT images. An algorithm for the lumen and inner wall segmentations, and wall thickness detection was developed and tested on 10 ruptured and 10 unruptured AAAs. Reproducibility and repeatability of the algorithm were determined by comparing manual tracings made by two observers to contours made automatically by the algorithm itself. There was a high correspondence between automatic and manual area measurements for the lumen (r = 0.96) and between users (r = 0.98). Based on statistical analyses, the algorithm tends to underestimate the lumen area when compared to both observers.
