Simulation and Optimization of JPEG and Motion JPEG

The aim of this project was to examine the optimization possibilities of the standard JPEG code and to extend the capabilities of JPEG by adding a Motion JPEG coder. In the beginning of the project the possibility of optimization of the JPEG code, as written in C, was examined along with a thorough search for algorithms that could perform specific, time consuming tasks faster. Along with the study of the JPEG code, detailed results were obtained on the performance of each function in the algorithm for both encoding and decoding parts. From the study of the currently used algorithms, the performance results and the search for newer, more efficient algorithms, JPEG was found to perform quite well. The focus of the project was then directed in the implementation of the Motion JPEG addition. In the first steps of dealing with this task, various video coding standards such as H.263 and MPEG-2 had to be carefully studied. A complete motion JPEG coder consisting of a video encoder and decoder was finally implemented. The results were tested using a sequence of frames taken as parameters of the program, in line with the standard JPEG input structure.
