Abstract:

<p>This thesis investigates possibilities to perform image interpolation on an FPGA instead of on a graphics card. The images will be used for 3D display on Setred AB’s screen and an implementation in firmware will hopefully give two major advantages over the existing rendering methods. First, an FPGA can handle big amounts of data and perform a lot of calculations in parallel. Secondly, the amount of data to transfer is drastically increased after the interpolation and with this, a higher bandwith is required to transfer the data at a high speed. By moving the interpolation as close to the pr

Abstract:

<p>This thesis investigates how disparity estimation may be used to visualize an object on a 3D-screen. The first part looks into different methods of disparity estimation, and the second part examines different ways to visualize an object from one or several stereo pairs and a disparity map. Input to the system is one or several stereo pairs, and output is a sequence of images of the input scene but from more angles. This sequence of images can be shown on Setred AB's 3D-screen. The system has high real time demands and the goal is to do the disparity estimation and visualization in real time

Abstract:

In Geographic Information System (GIS) applications, aster data constitutes one of the major data types. The displaying of the raster data has an important part in GIS applications. Digital Terrain Elevation Data (DTED) is one of the raster data types, which is used as the main data source in this thesis. The DTED data is displayed on the screen as digital images as a pixel value, which is represented in gray scale, corresponding to an elevation (texel). To draw the images, the texel values are mostly interpolated in order to perform zoom-in and/or zoom-out operations on the concerned area. W

Abstract:

This thesis presents a new system that reconstructs the 3D representation of dental casts. To maintain the integrity of the 3D representation, a standard model is built to cover the blind spots that the camera cannot reach. The standard model is obtained by scanning a real human mouth model with a laser scanner. Then the model is simplified by an algorithm which is based on iterative contraction of vertex pairs. The simplified standard model uses a local parametrization method to obtain the curvature information. The system uses a digital camera and a square tube mirror in front of the camera

Abstract:

The dissertation thesis deals with 3D reconstruction of the temporomandibular joint from 2D slices of tissue obtained by magnetic resonance. The current practice uses 2D MRI slices in diagnosing. 3D models have many advantages for the diagnosis, which are based on the knowledge of spatial information. Contemporary medicine uses 3D models of tissues, but with the temporomandibular joint tissues there is a problem with segmenting the articular disc. This small tissue, which has a low contrast and very similar statistical characteristics to its neighborhood, is very complicated to segment. For th

Abstract:

The visualization of a 3D image obtained from computerized tomography examinations has shown itself to be an important factor for increasing the quality of medical diagnoses and, consequently, treatment efficacy. There already exist on the market, several visualization softwares, which use different techniques to show the 3D tomography image. However, to show a high quality 3D image, sophisticated devices must be used to obtain slices, close to one another, thus increasing the incidence of X-ray given to the patient. An interpolation slice method which resulted from the TC examination produces

It is not only an illustrative way for common people, but also a comprehensive method to interpret results of the work. Geologists, geophysics engineers and GIS experts sometimes need to visualize an area to accomplish their researches. It can show how sample data are distributed over the area and therefore they can be applied as suitable approach to validate the result. Among different 3D modeling methods, some are expensive or complicated. Therefore, s

Depuis quelques décennies, les communautés d'informatique graphique et de vision ont contribué à l'émergence de technologies permettant la numérisation d'objets 3D. Une demande grandissante pour ces technologies vient des acteurs de la culture, notamment pour l'archivage, l'étude à distance et la restauration d'objets du patrimoine culturel : statuettes, grottes et bâtiments par exemple. En plus de la géométrie, il peut être intéressant de numériser la photométrie avec plus ou moins de détail : simple texture (2D), champ de lumière (4D), SV-BRDF (6D), etc. Nous formulons des solutions concrète

Abstract:

Esta tese apresenta um novo método para interpolação de vistas em vídeos usando câmeras ao longo de um baseline baseado em uma triangulação 2D. A imagem de referência é primeiramente particionada em regiões triangulares usando informação de bordas e escala, visando colocar vértices ao longo das bordas da imagem e aumentar o número de triângulos em regiões texturadas. Um algoritmo de casamento de regiões é então usado para encontrar a disparidade inicial de cada triângulo, e uma etapa de refinamento é aplicada para mudar a disparidade nos vértices dos triângulos, gerando um mapa de disparidade

Abstract:

Based on the symmetry assumption of human faces, we mirror the original non-frontal face image to obtain another basis image. A 3D generic head model is used to estimate the face pose by manually labeling a small set of feature points as input to the system. The dense matching between two basis images is computed from 2D-3D RBF mapping, 3D-2D perspective projection and optical flow computation. To solve the self-

This segmentation can provide the location information of tumor for doctors during operation and improve the accuracy of operation. Because the images obtained by 2D ultrasound scans are irregularly spaced most of the time, it is necessary to interpolate them into regularly spaced 3D images so that image processing techniques for 2D images can be generalized directly with fast computation speed. Spline interpolation is used in this study. Generalized cross validation i
