摘要

Multimedia data compression is a challenging situation for compression technique, due to the possibility of loss of data as well as it require large amount of storage place. The minimization of storage place and proper transmission of these data need compression. In this dissertation we proposed a block based DWT image compression technique using genetic algorithm and HCC code matrix. The HCC code matrix compressed into two different set redundant and non-redundant which generate similar pattern of block coefficient. The similar block coefficient generated by particle of swarm optimization. The process of particle of swarm optimization is select for the optimal block of DWT transform function. For the experimental purpose we used some standard image such as Lena, Barbara and cameraman image. The size of resolution of this image is 256*256. The source of image is Google.
