Traditional image coding technology mainly uses the statistical redundancy between pixels to reach the goal of compressing. The research on wavelet transform image coding technology has made a rapid progress. Because of its high speed low memory requirements and complete reversibility digital wavelet transform IWT has been adopted by new image coding standard JPEG 2000. The embedded zero tree wavelet EZW algorithms have obtained not bad effect in low bit-rate image compression. Set Partitioning in Hierarchical Trees SPIHT is an improved version of EZW and has become the general standard of EZW So In this paper we are proposing DWT and SPIHT Algorithm with Huffman encoder for further compression and Retinex Algorithm to get enhanced quality improved image.
