STUDY OF IMAGE COMPRESSION TECHNIQUE BASED ON THE SPIHT ALGORITHEM
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 5
Abstract
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 basic 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).
