Comparison of algorithms for image compression

The EZW and SPIHT coding are remarkably effective image compression algorithms having the property that the bits in the compressed bit stream are generated in the order of importance yielding a fully embedded code, hi this project the coding techniques for EZW (Embedded zero wavelet coding) and SPHIT (Set partitioning in hierarchical trees) have been developed. The performance analysis of both the algorithms in terms of compression ratio and peak signal to noise ratio (PSNR) for different level of Wavelet decomposition has been implemented with the comparison of results for the images This project provides an easy and efficient method for qualitative and quantitative comparison of different algorithms that can be used for image compression.
