Image compression is the process of reducing the size of image is known as image compression. There are two mechanisms to compress image. Here the Cabac and Quadtree Techniques are applied to compress the image. Coding of data symbol consists of several stages and a tree data structure is known as quadtree. In quadtree, there are exactly four children in every internal node. Quadtrees has been known as the analog of octrees which are two-dimensional. It has been used for partition of a two-dimensional space. It has been done by recursively subdividing it into four quadrants or regions. There are several researches made in the field of image compression. Such researches are also considered in the chapter. This work would be considered best verified and simulated. It would synthesize CABAC decoding mechanism using Matlab. It would be capable to execute complete CABAC Algorithm as future work. The research work would be beneficial in future time. The result of the research work has proved that the proposed techniques are much better techniques than the traditional.
