An overview of Adaptive Binary Range Coder with low memory requirement

There are number of coders used in video or image compression techniques such as MQ - coder used in JPEG2000,Q - coder used in JPEG. In proposed system,the virtual sliding window is used for probability estimation,which does not uses lookup table. Forim proving compression performance a new adaptive window size selection algorithm is used . As compared to the bi nary range coder with a single window,the proposed algorithm provides a faster probability estimation and adaptation at the initial encoding and decoding stage,and more precise probability estimation for very low entropy binary sources. In proposed system uses virtual sliding window,therefore the memory requirement is less as compared to previous system. The power consumption of proposed system is measured by using the Xi linx X power analyzer. The power consumption is reduced in proposed Adaptive Binary Range Coder as com pared to previous coders like M - coder and M Q - coder.
