"The purpose of image compression is to represent images with less data in order to save storage costs or transmission time and costs. JPEG which stands for Joint Photographic Experts Group is one of the many standards for compressing still images and it is the most widely used standard. The work done as part of this thesis is mainly aimed at analyzing some of the variations of the JPEG standard. Some of the features include incorporating one of the motion estimation and compensation techniques of MPEG in JPEG, taking the differences of the blocks which are side-by-side and, encoding and decoding them, etc. Two different variations of JPEG algorithm have been analyzed in this work. The first model called the JPEG/MPEG model using the Full-search motion estimation and compensation technique of MPEG in JPEG. The second model assumes that the side-by-side block are related to each other and takes the difference between the blocks and does the JPEG compression work on the difference block. The above two models have been analyzed to see the trade-off between the amount of memory they will save and the quality of the image they will lose compared to the normal JPEG method. The analysis of the above two models has been done on a set of 18 grayscale images. The results from both the models were very promising for most of the images. Nearly all the work was done using the MATLAB tool"--Abstract, page iii.
