. Examples of the main emerging concepts and theories in field of 2D&3D vision systems have been presented: stereo vision and epipolar geometry c. A presentation of the emerging paradigms in the field has been done: that of compressive sampling for video data acquisition and, respectively, that of distributed video coding d. A study of the most important distributed video coding architectures (the „Stanford” and the „PRISM” architecture) together with their improvements and extensions has been performed. e. A comparison between the existing implementations of codec designs based on the distributed video coding paradigm has been realised. f. An algorithm based on the concept of „depth from defocus” has been implemented. g. An new algorithm for extracting the depth information form light polarisation has been proposed and implemented h. An evaluation of the proposed algorithm for depth extraction from light polarisation has been performed based on various sets of measurements and the depth map was constructed for the test scenes i. An algorithm for video processing using lookup tables has been developed together with the algorithm for computing and writing data in these tables j. The algorithm for real-time video processing using look-up tables has been implemented and simulated in software, at frame level. k. An experimental, proof-of-concept model, using FPGA technology and look-up tables has been implemented; the prototype, developed with contributions from the author, is protected by official copyright laws and is in the intellectual property of Netherland Grass Valley company. From the point of view of the economical value of the research outcome, the proposed algorithm for depth from light polarisation offers the premises for creating new photo / video cameras able to capture brightness but also depth information from the scene. Also, the research results presented in chapter 5, of real time video processing using FPGAs and LUTs, was integrated in the latest LDK 8xxx series of professional video cameras launched in 2012 by the Netherland Grass Valley company. The main published papers with results from the thesis that were presented to the scientific community so far are the following: S.N. Meza, K.J. Damstra, J.V. Rooy, S.

S.N. MEZA ”Distributed Video Coding” – presentation at the „16th Summer School on Image Processing SSIP” 2008 Technical University of Vienna, Austria. Future development of the research done by the author aim at optimising the implementation of the proposed algorithm of depth information extraction from light polarisation and its extension to video. Likewise, an experimental model for a device capable of 3D (brightness and depth) data acquisition will be realised based on the result of chapter 4. By sensor level integration of the polariser filter, direct capturing of the depth information from a single perspective will be possible, without any intervention on scene illumination or projecting any scanning pattern. 7
