STUDY OF IMAGE COMPRESSION TECHNIQUE BASED ON THE SPIHT ALGORITHEM

In this paper, we study the compression technique. That is, Set Partitioning in Hierarchical Trees (SPIHT). This compression technique is based on the wavelet transform .A wavelet is a small wave which has its energy concentrated in time. It gives a tool for the analysis of non - stationary signal. Wavelet transform which decompose a signal into a set of basis function .This basi c function is called the Wavelet. Here we see that SPIHT compression technique can preserve better visual characteristics of an original Image in the sense of PSNR (peak signal to noise ratio).
