This paper presents an approach for an Enhanced Image Compression Method using Partial SPIHT Algorithm. This is based on the progressive image compression algorithm, SPIHT which is an extension of Shapiro's Embedded Zerotree Wavelet Algorithm. The proposed Partial SPIHT Algorithm overcomes the difficulty of SPIHT that loses its efficiency in transmitting lower bit planes. In this paper, we include integer wavelet transformation and region of interest coding to Partial SPIHT and hence make it more superior to SPIHT and EZW Algorithm and it is proved with the results.
