Abstract:
AbstractThe subclass Camerata (Crinoidea, Echinodermata) is a major group of Paleozoic crinoids that represents an early divergence in the evolutionary history and morphologic diversification of class Crinoidea, yet phylogenetic relationships among early camerates remain unresolved. This study conducted a series of quantitative phylogenetic analyses using parsimony methods to infer relationships of all well-preserved Ordovician camerate genera (52 taxa), establish the branching sequence of early camerates, and test the monophyly of traditionally recognized higher taxa, including orders Monobathrida and Diplobathrida. The first phylogenetic analysis identified a suitable outroup for rooting the Ordovician camerate tree and assessed affinities of the atypical dicyclic family Reteocrinidae. The second analysis inferred the phylogeny of all well-preserved Ordovician camerate genera. Inferred phylogenies confirm: (1) the Tremadocian genera Cnemecrinus and Eknomocrinus are sister to the Camerata; (2) as historically defined, orders Monobathrida and Diplobathrida do not represent monophyletic groups; (3) with minimal revision, Monobathrida and Diplobathrida can be re-diagnosed to represent monophyletic clades; (4) family Reteocrinidae is more closely related to camerates than to other crinoid groups currently recognized at the subclass level; and (5) several genera in subclass Camerata represent stem taxa that cannot be classified as either true monobathrids or true diplobathrids. The clade containing Monobathrida and Diplobathrida, as recognized herein, is termed Eucamerata to distinguish its constituent taxa from more basally positioned taxa, termed stem eucamerates. The results of this study provide a phylogenetic framework for revising camerate classification, elucidating patterns of morphologic evolution, and informing outgroup selection for future phylogenetic analyses of post-Ordovician camerates.

Abstract:
This paper presents an algorithm for camera localization using trajectory estimation (CLUTE) in a distributed network of nonoverlapping cameras. The algorithm recovers the extrinsic calibration parameters, namely, the relative position and orientation of the camera network on a common ground plane coordinate system. We first model the observed trajectories in each camera's field of view using Kalman filtering, then we use this information to estimate the missing trajectory information in the unobserved areas by fusing the results of a forward and backward linear regression estimation from adjacent cameras. These estimated trajectories are then filtered and used to recover the relative position and orientation of the cameras by analyzing the estimated and observedexitandentrypoints of an object in each camera's field of view. The final configuration of the network is established by considering one camera as a reference and by adjusting the remaining cameras with respect to this reference. We demonstrate the algorithm on both simulated and real data and compare the results with state-of-the-art approaches. The experimental results show that the proposed algorithm is more robust to noisy and missing data and in case of camera failure.

Abstract:
Most modern cameras allow captured images to be saved in two color spaces: (1) raw-RGB and (2) standard RGB (sRGB). The raw-RGB image represents a scene-referred sensor image whose RGB values are specific to the color sensitivities of the sensor's color filter array. The sRGB image represents a display-referred image that has been rendered through the camera's image signal processor (ISP). The rendering process involves several camera-specific photo-finishing manipulations intended to make the sRGB image visually pleasing. For applications that want to use a camera for purposes beyond photography, both the raw-RGB and sRGB color spaces are undesirable. For example, because the raw-RGB color space is dependent on the camera's sensor, it is challenging to develop applications that work across multiple cameras. Similarly, the camera-specific photo-finishing operations used to render sRGB images also hinder applications intended to run on different cameras. Interestingly, the ISP camera pipeline includes a colorimetric conversion stage where the raw-RGB images are converted to a device-independent color space. However, this image state is not accessible. In this paper, we advocate for the ability to access the colorimetric image state and recommend that cameras output a third image format that is based on this device-independent colorimetric space. To this end, we perform experiments to demonstrate that image pixel values in a colorimetric space are more similar across different makes and models than sRGB and raw-RGB.

Abstract:
Transportation agencies have invested significantly in extensive closed-circuit television (CCTV) systems to monitor freeways in urban areas. While thes systems have proven to be very effective in supporting incident management, they do not support the collection of quantitative measures of traffic conditions. Instead, they simply provide images that must be interpreted by trained operators. While there are several video image vehicle detection systems (VIVDS) on the market that have the capability to automatically derive traffic measures fro video imagery, these systems require the installation of fixed-position cameras. Thus, they have not been integrated with the existing moveable CCTV cameras. VIVDS camera positioning and calibration challenges were addressed and a prototype machine-vision system was developed that successfully integrated existing moveable CCTV cameras with VIVDS. Results of testing the prototype are presentedindicating that when the camera’s initial zoom level was kept between ×1 and ×1.5, the camera consistently could be returned to its original position with a repositioning accuracy of less than 0.03 to 0.1 regardless of the camera’s displaced pan, tilt, or zoom settings at the time of repositioning. This level of positional accuracy when combined with a VIVDS resulted in vehicle count errors of less than 1%.

Abstract:
Knowledge about the interior and exterior camera orientation parameters is required to establish the relationship between 2D image content and 3D object data. Camera calibration is used to determine the interior orientation parameters, which are valid as long as the camera remains stable. However, information about the temporal stability of low-cost cameras due to the physical impact of temperature changes, such as those in smartphones, is still missing. This study investigates on the one hand the influence of heat dissipating smartphone components at the geometric integrity of implemented cameras and on the other hand the impact of ambient temperature changes at the geometry of uncoupled low-cost cameras considering a Raspberry Pi camera module that is exposed to controlled thermal radiation changes. If these impacts are neglected, transferring image measurements into object space will lead to wrong measurements due to high correlations between temperature and camera’s geometric stability. Monte-Carlo simulation is used to simulate temperature-related variations of the interior orientation parameters to assess the extent of potential errors in the 3D data ranging from a few millimetres up to five centimetres on a target in X- and Y-direction. The target is positioned at a distance of 10 m to the camera and the Z-axis is aligned with camera’s depth direction.

<p><strong>Abstract.</strong> On space remote sensing stereo mapping field, the angle variation between the star sensor’s optical axis and the earth observation camera’s optical axis on-orbit affects the positioning accuracy, when optical mapping is without ground control points (GCPs). This work analyses the formation factors and elimination methods for both the star sensor’s error and the angles error between the star sensor’s optical axis and the earth observation camera’s optical axis. Based on that, to improve the low attitude stability and long calibration time necessary of current satellite cameras, a method is then proposed for real-time on-orbit calibration of the angles between star sensor’s optical axis and the earth observation camera’s optical axis based on the principle of auto-collimation. This method is experimentally verified to realize real-time on-orbit autonomous calibration of the angles between the star sensor’s optical axis and the earth observation camera’s optical axis.</p>

Digital cameras have been widely used in the areas of road transportation, railway transportation as well as security system. To address the position of digital camera in these fields this paper proposed a geometry calibration method based on feature point extraction of arbitrary target. Under the meaning of the questions, this paper first defines four kinds of coordinate system, that is the world coordinate system. The camera's optical center of the coordinate system is the camera coordinate system, using the same point in different coordinate system of the coordinate transformation to determine the relationship between world coordinate system and camera coordinate. And thus determine the camera's internal parameters and external parameters, available transformation matrix and translation vector indicated by the camera's internal parameters of the external parameters and the establishment of a single camera location model. According to the model, using the camera's external parameters to be on the target circle center point in the image plane coordinates.

Cabiati, Alessandro. "Baudelairism and modernity in the poetry of Scapigliatura." Thesis, University of Edinburgh, 2017. http://hdl.handle.net/1842/25764.

Abstract:
In the 1860s, the Italian Scapigliati (literally ‘the dishevelled ones’) promoted a systematic refusal of traditional literary and artistic values, coupled with a nonconformist and rebellious lifestyle. The Scapigliatura movement is still understudied, particularly outside Italy, but it plays a pivotal role in the transition from Italian Romanticism to Decadentism. One of the authors most frequently associated with Scapigliatura in terms of literary influence as well as eccentric Bohemianism is the French poet Charles Baudelaire, certainly amongst the most innovative and pioneering figures of nineteenth-century European poetry. Studies on the relationship between Baudelaire and Scapigliatura have commonly taken into account only the most explicit and superficial Baudelairian aspects of Scapigliatura’s poetry, such as the notion of aesthetic revolt against a conventional idea of beauty, which led the Scapigliati to introduce into their poetry morally shocking and unconventional subjects. Furthermore, these studies have not focused on drawing a detailed and systematic picture that portrays the connections not only between Baudelaire and the poets of Scapigliatura, but also among the Scapigliati themselves. As a result, the true extent of Baudelaire’s influence has not been acknowledged. This study strives to fill the gaps in the existing scholarship. My thesis posits that Baudelaire’s influence on the poetry of Scapigliatura, almost exclusively related to the first two editions of the verse collection Les Fleurs du Mal, is more profound and substantial than scholarship has heretofore recognised. The thesis consists of three chapters, each dedicated to one of the three most important poets of Scapigliatura, namely Arrigo Boito, Emilio Praga, and Giovanni Camerana. The investigation of Baudelaire’s influence on the Scapigliati is conducted both individually, searching for Baudelairian features in their work, and comparatively, contrasting differences and aiming to locate similarities. The main focus is on the major poetic works that are strictly related to the phases in these poets’ careers when they were associated with Scapigliatura: Boito’s Il libro dei versi and Re Orso; Praga’s Tavolozza and Penombre; and Camerana’s poems written between 1863 and 1869. My aim is to establish if there was what can be called a ‘Baudelairian school’ within Scapigliatura. Ultimately, I argue that the relationship between Baudelaire and the poetry of Scapigliatura is more complex than has previously been understood. I demonstrate a vast and wide-ranging influence – on a conceptual, lexical, and stylistic level – on the three poets discussed in this work, which can be traced back to the very beginning of their careers in the early 1860s. Far from being simply an element of aesthetic and moral rebellion in order to épater le bourgeois, the Baudelairism of Boito, Praga, and Camerana in their Scapigliatura years accomplished two ends: on the one hand, it preserved some of the more traditional aspects of Baudelaire’s poetry, which have been largely overlooked by Italian literary scholarship on Scapigliatura; on the other hand, it introduced a thematic and formal modernity into Italian poetry, paving the way for the Decadent movement as well as the twentieth-century avant-gardes.

Abstract:
Ce travail se divise en deux parties comptant chacune trois chapitres. La première partie, du mot aux thèmes, réfléchit sur les origines du nom Scapigliatura afin de comprendre pourquoi ce terme désigne un mouvement littéraire et artistique, qui eut Milan pour foyer, et se développa entre 1860 et 1885. Le roman de Cletto (1828-1906), La Scapigliatura e il 6 Febbraio (1862), et le rôle de la presse dans la fortune de ce mot sont étudiés au premier chapitre, Scapigliatura et sémantique. Dans le second, au temps de la Scapigliatura, une perspective diachronique permet de présenter les principaux auteurs de ce courant. Quelques textes qui ont valeur de manifeste y sont également étudiés. Le troisième chapitre, identité de la Scapigliatura, se propose de dégager les traits caractéristiques de la Scapigliatura, à travers la formation culturelle de ses représentants et quelques thèmes fédérateurs. A partir des conclusions de la première partie, nous avons, dans la seconde, regards sur trois itinéraires, mené des analyses plus approfondies sur trois auteurs : Igino Ugo Tarchetti (1839-1869), Arrigo Boito (1842-1918), Giovanni Camerana (1845- 1905). Pour I. Ugo Tarchetti seuls les textes narratifs, ils forment la part la plus importante de son œuvre, sont examinés. Nous y observons les procédés narratifs employés par l'auteur, ainsi que les formes et fonctions de l'exotisme présent dans nombre de ses récits. Pour Arrigo Boito nous travaillons sur un corpus restreint, quatre nouvelles, qui sont, cependant, très révélatrices de la forma mentis de leur auteur. Quant à l'œuvre de Giovanni Camerana elle se résume à un recueil de poèmes et à des commentaires de tableaux, publiés dans une revue d'art. Après avoir souligné les thèmes récurrents de son œuvre poétique, nous proposons une étude des influences réciproques entre l'écriture critique et l'écriture poétique de l'auteur
This work falls into two parts, each one comprising three chapters. The first part, from the word to the themes, is dedicated to the study of the origins of the noun Scapigliatura in order to understand why that term designates a literary and artistic movement which started in Milan and spanned the years between 1860 and 1885. The novel by Cletto Arrighi (b. 1828 - d. 1906), la Scapigliatura e il 6 febbraio (published in 1862) and the role of the press in popularizing that term are studied in the first chapter, Scapigliatura and semantics. In the second chapter, at the time of the Scapigliatura, a diachronic perspective permits an introduction to the main authors of that movement. A few texts, which have manifesto value, are also studied. The third chapter, the identity of the Scapigliatura, aims at defining the characteristic features of the Scapigliatura by studying the cultural upbringing of its representatives and some themes they have in common. In the second part, an outlook on three itineraries, we used the conclusions of the first pat to make deeper analyses of three authors, I. Ugo Tarchetti (b. 1839- d. 1869), Arrigo Boito (b. 1842- d. 1918), and Giovanni Camerana ( b. 1845- d. 1905). Concerning I. Ugo Tarchetti only his narrative texts have been examinated, since they constitute the major part of his works. We have studied the narrative processes used by the author, as well as the forms and functions of the exotism recurrent in many of his writings. Concerning Arrigo Boito, we have worked on four short stories only, which, however, reveal much about the author's forma mentis. As for Giovanni Camerana's works, they are limited to a collection of poems and commentaries on paintings, published in an art review. After having underlined the themes recurring in his poetical works, we propose a study of the reciprocal influences between the author's critical and poetical writings

Abstract:
Developments in event-based camera technology and their recent increase in pixel count raised the question of whether resolution helps the accuracy and performance of algorithms. This thesis studies the impact of resolution on optical flow estimation for event-based cameras. For this purpose, we created a data set containing a mix of synthetic scenes and real camera recordings with ground truth available. For the modeling of low-resolution data, we designed three different downsampling algorithms. The camera used for the real scene recordings was the Prophesee (CSD3SVCD), which was determined to be the best out of the current state-of-the-art cameras in a prestudy. The camera investigation evaluated the camera’s performance in terms of temporal and spatial accuracy. In order to answer the question, whether resolution benefits the accuracy of optical flow estimation, we ran a total of 13 algorithms variations from four algorithm families (Lucas-Kanade [1, 2], Local-Planes fitting [2, 3], direction-selective filter [2, 4] and patch match [5]) on the data set. We then analysed their performance in terms of processing time, output density, angular error, endpoint error and relative endpoint error. The results show that no global correlation between resolution and accuracy across all algorithms can be identified. However, methods show individually different behaviour on different data. The best performing methods, the patch match algorithms, seemed to prefer the less dense downsampled data. The evaluation also showed that rather than resolution, the specific characteristics of the data seemed to have a larger impact on accuracy. Thus denoised data might increase accuracy more than a change of resolution.
De senaste utvecklingarna inom händelsebaserad kamerateknologi och deras nyligen utökade mängd pixlar ställer frågan om denna högre upplösning påverkar precision samt prestanda för algoritmer. Den här rapporten studerar påverkan av upplösning på optiskt flödes-algoritmer för händelsebaserade kameror. För att göra detta skapas en dataupsättning av riktiga och syntetiska scener, där det sanna optiska flödet är känt. För att modellera den lågupplösta datan används tre olika nedskalningsalgoritmer. Kameran som används för att spela in de riktiga scenerna var Prophesee (CSD3SVCD), som vi avgjorde var den bästa av de nuvarande existerande kamerorna i en förstudie. I förstudien bedömde vi kamerornas precision i tid samt rymd. För att besvara vår huvudsakliga fråga testades totalt 13 algoritmvariationer från fyra algoritmfamiljer (Lucas-Kanade [1, 2], Local Planes fitting [3, 2], direction-selective filter [4, 2] och patch match [5]). Vi analyserar deras prestanda i beräkningstid, densitet av vektorer, ändpunktsfel, relativt ändpunktsfel och vinkelfel. Resultaten visar ingen global trend över alla algoritmer för precision av optiskt flöde baserat på upplösning. Individuella trender kan dock skönjas inom algoritmfamiljer. Den bäst presterande algoritmfamiljen, patch match, verkade föredra de mindre täta typerna av nedskalning. Utvärderingen visar också att över upplösning så verkar datans specifika karaktäristik ha större påverkan på precision. Därför kan brusreducerad data ha mer påverkan på en algoritms precision än en ändrad upplösning.

The aim of this thesis is to provide insight into how YouTube audiences perceive theprofessionalization of vlog production styles and what happens to the parasocial relationshipbetween viewer and vlogger, especially in relation to authenticity, in relation to this. This is doneby a thematic analysis of comments on Valeria Lipovetsky’s YouTube video “We Need ToTalk”, which serves as a case study. The analysis is done in background to theories ofprofessionalization of influencers, parasocial relationships and authenticity. The results show thatthere is a tension between the perceived authenticity of the vlogger and the professionalizationof vlog production style that is affecting the parasocial relationship between viewer and vloggernegatively. The distinguished themes point to vlogs filmed by a camera team being perceived toresemble reality television which is making the viewers feel disconnected with the vlogger. It isrevealed that the audience prefers vlogs where the vlogger is holding the camera themselves, asthat is perceived as more personal and authentic.

Their development depends heavily on the quality of sensor data, a detailed measure of which is often up to the automotive manufacturers to derive, since the original equipment manufacturers (OEMs) may not disclose it on trade secrecy grounds. A model would not only provide a measure of the real-world performance of the sensor, but would also enable a higher degree of simulation accuracy which is vital to active safety function development. This is largely due to the high cost and risk involved in testing, a significant part of which is possible to be done in simulation alone. This thesis is an effort to derive a sensor model on behalf of Volvo Trucks of the performance of one of the most crucial sensors in current active safety - a lane detection camera.The work is focused on investigating approaches for modelling and simulation implementation of the lane estimation process within the black-box camera using reverse-engineering of the sensor's principles of operation. The main areas of analysis to define the factors that affect performance are the optics, image sensor, software and computer vision algorithms, and system interface. Each of them is considered separately and then methods for modelling are proposed, motivated, and derived accordingly. Finally, the finished model is evaluated to provide a measure of work success and a basis for further development.
Säkerhet är idag, tillsammans med effektivitet, en av de två starkaste förändringskrafterna i bilvärlden. Störst fokus ligger på avancerade aktiva säkerhetsfunktioner. Deras utveckling beror till stor del på kvaliteten på sensordata. En detaljerad modell för sensordata är ofta upp till fordonstillverkarna att härleda, eftersom tillverkare av sensorn ofta inte vill lämna ut sådan information. En modell ger inte bara ett mått på den verkliga prestandan hos sensorn, men ger också möjlighet till en högre grad av simuleringsnoggrannhet vilket är avgörande för utveckling av aktiva säkerhetsfunktioner. Tester är kostsamma och medför risker och en noggrann modell gör att tester kan utföras i simulering vilket minskar kostnader och risker. I denna avhandling härleds en sensormodell på uppdrag av Volvo Lastvagnar. Sensorn i fråga är en av de viktigaste sensorerna i det nuvarande aktiva säkerhetssystemet, kameran för att följa en körfil på vägen. Arbetet är fokuserat på undersökning av metoder för modellering och simulering av processen för filföljning baserat på sensorns funktionsprinciper. De viktigaste områdena för analys för att definiera de faktorer som påverkar prestanda är optik, bildsensorn, programvara, datorseendealgoritmer och systemets gränssnitt. Var och en av dessa behandlas separat och sedan föreslås och motiveras metoder för modellering. Slutligen utvärderas den färdiga modellen för att ge ett mått på hur framgångsrikt arbetet varit samt för att lägga en grund för ytterligare utveckling.

The thesis work was carried out at Volvo Group Trucks Technology in Göteborg, Sweden. Supervisor for GTT: Mansour Keshavarz.

Abstract:
AbstractOptical quality control of MEMS and microsystems is challenging as these structures are micro-scale and three dimensional. Here we lay out different optical systems that can be used for 3D optical quality control in general and for such structures in particular. We further investigate one of these technologies – plenoptic cameras and characterize them for the described task, showing advantages and disadvantages. Key advantages are a huge increase in depth of field compared to conventional microscope camera systems allowing for fast acquisition of non-flat systems and secondly the resulting total focus images and depth maps. Finally we conclude that these advantages render plenoptic cameras a valuable technology for the application of quality control.

Abstract:
Abstract Most surveillance camera systems are still controlled and monitored by humans. Smart surveillance camera systems are proposed to automatically understand the scene captured, identify the objects of interest, detect the abnormality, etc. However, most surveillance cameras are either wide-angle or pan-tilt-zoom (PTZ). When the cameras are in the wide-view mode, small objects can be hard to be recognized. On the other hand, when the cameras are zoomed-in to the object of interest, the global view cannot be covered and important events outside the zoomed view will be missed. In this paper, we proposed a system composed of a wide-angle camera and a PTZ camera. The system is able to capture the wide-view and the zoomed-view at the same time, taking the advantages from both views. A real-time human detection and identification algorithm based on a neural network is developed. The system can efficiently and effectively recognize humans, distinguish different identities, and follow the person of interest using the PTZ camera. A multi-target multi-camera (MTMC) system is developed based on the original system. In the MTMC system, multiple cameras are placed at different places to look at different views. The same person shown in any camera can be recognized as the same person while different persons can be distinguished among all the cameras.

Abstract:
Visual analytics applications often rely on target tracking across a network of cameras for inference and prediction. A network of cameras generates immense amount of video data and processing it for tracking a target is highly computationally expensive. Related works typically use data association and visual re-identification techniques to match target templates across multiple cameras. In this thesis, I propose to formulate this scheduling problem as a Markov Decision Process (MDP) and present a reinforcement learning based solution to schedule cameras by selecting one where the target is most likely to appear next. The proposed approach can be learned directly from data and doesn't require any information of the camera network topology. NLPR MCT and DukeMTMC datasets are used to show that the proposed policy significantly reduces the number of frames to be processed for tracking and identifies the camera schedule with high accuracy as compared to the related approaches. Finally, I will be formulating an end-to-end pipeline for target tracking that will learn a policy to find the camera schedule and to track the target in the individual camera frames of the schedule.

Abstract:
Flux distributions from solar field collectors are typically evaluated using a beam characterization system, which consists of a digital camera with neutral density filters, flux gauge or calorimeter, and water-cooled Lambertian target panel. The pixels in camera image of the flux distribution are scaled by the flux peak value measured with the flux gauge or the total power value measured with the calorimeter. An alternative method, called PHLUX developed at Sandia National Laboratories, can serve the same purpose using a digital camera but without auxiliary instrumentation. The only additional information required besides the digital images recorded from the camera are the direct normal irradiance, an image of the sun using the same camera, and the reflectivity of the receiver or target panel surface. The PHLUX method was evaluated using two digital cameras (Nikon D90 and D3300) at different flux levels on a target panel. The performances of the two cameras were compared to each other and to measurements from a Kendall radiometer. For consistency in comparison of the two cameras, the same focal length lenses and same number of neutral density filters were used. Other camera settings (e.g., shutter speed, f-stop, etc.) were set based on the aperture size and performance of the cameras. The Nikon D3300 has twice the number of pixels as the D90. D3300 provided higher resolution, however, due to the smaller pixel sizes the images were noisier, and the D90 with larger pixels had better response to low light levels. The noise in the D3300, if not corrected, could result in gross overestimation of the irradiance calculations. After corrections to the D3300 flux images, the PHLUX results from the two cameras showed they agreed to within 8% for a peak flux level of 1000 suns on the target, and less than 10% error in the peak flux when compared to the Kendall radiometer.

Abstract:
This work aims to present an autonomous vehicle navigation system, based on an End-to-End Deep Learning approach, and to study the impact of different image input configurations to the system performance. The proposed methodology in this work was to adoptand test different configurations of RGB and Depth images captured from a Kinect device. We adopted a multi-camera system, composed by 3 cameras, with different RGB and/or Depth input configurations. Two main systems were developed in order to study and validade de different input configurations: the first one based on a realistic simulator and the second one based on a mini-car (small scale vehicle). Starting with the simulations, it was possible to choose the best camera/input configuration, then we validated that using the real vehicle (mini-car) with real sensors/cameras. The experimental results demonstrated that a multi-camera solution, based on 3 cameras, allow us to obtain better autonomous navigation control results in a End-to-End Deep Learning based approch, with a very small final error when using the proposed camera configurations.

Abstract:
Studies of wave climate, extreme ocean events, turbulence, and the energy dissipation of breaking and non-breaking waves are closely related to the measurements of the ocean surface. To gauge and analyze ocean waves on a computer, we reconstruct their 3-D model by utilizing the concepts of stereoscopic reconstruction and variational optimization. This technique requires a pair of calibrated cameras — cameras whose parameters are estimated for the mathematical projection model from space to an image plane — to take videos of the ocean surface as input. However, the accuracy of camera parameters, including the orientations and the positions of cameras as well as the internal specifications of optics elements, are subject to environmental factors and manual calibration errors. Because the errors of camera parameters magnify the errors of the 3-D reconstruction after projection, we propose a novel algorithm that refines camera parameters, thereby improving the accuracy of variational 3-D reconstruction. We design a multivariate error function that represents discrepancies between captured images and the reprojection of the reconstruction onto the images. As a result of the iteratively diminished error function, the camera parameters and the reconstruction of ocean waves evolve to optimal values. We demonstrate the success of our algorithm by comparing the reconstruction results with the refinement procedure to those without it and show improvements in the statistics and spectrum of the wave reconstruction after the refinement procedure.

Abstract:
Micro-PIV experiments rely upon the use of a microscope to achieve the higher spatial resolution. However, several optical limitations are introduced at these scales [1–3]. In addition, due to the low illumination levels, micro-PIV experiments require the use of either a cooled CCD camera or an image intensifier to provide increased signal-to-noise ratio. Although CCD cameras offer superior sensitivity and signal to noise ratio, intensified CMOS cameras offer an attractive alternative for performing high frequency measurements. However, intensified cameras are known to introduce artifacts such as added background noise. This study examines these issues and the feasibility of employing such technologies for microPIV through the use of the IDT-X5 intensified CMOS camera, capable of 500 Hz at a resolution of 2352×1728 pixels, with pulse separations as low as 2μs.

Abstract:
[Extract from Executive Summary] This project, aimed at the development of a novel, automated mechanism for the collection of scallop stock data was a sub-part of the Scottish Inshore Fisheries Integrated Data Systems (SIFIDS) project. The project reviewed the state-of-the-art remote sensing (geophysical and camera-based) technologies available from industry and compared these to inexpensive, off-the -shelf equipment. Sea trials were conducted on scallop dredge sites and also hand-dived scallop sites. Data was analysed manually, and tests conducted with automated processing methods. It was concluded that geophysical acoustic technologies cannot presently detect individual scallop but the remote sensing technologies can be used for broad scale habitat mapping of scallop harvest areas. Further, the techniques allow for monitoring these areas in terms of scallop dredging impact. Camera (video and still) imagery is effective for scallop count and provide data that compares favourably with diver-based ground truth information for recording scallop density. Deployment of cameras is possible through inexpensive drop-down camera frames which it is recommended be deployed on a wide area basis for further trials. In addition, implementation of a ‘citizen science’ approach to wide area recording is suggested to increase the stock assessment across the widest possible variety of seafloor types around Scotland. Armed with such data a full, statistical analysis could be completed and data used with automated processing routines for future long-term monitoring of stock.
