OVERVIEW OF SPIHT BASED IMAGE COMPRESSION ALGORITHM

In today's World image compression technique is very essential because in this digitized world there is lot of use of image transmission which needs lots of space and time for transmission. Therefore, there are certain techniques which are used for image compression, in this paper we are introducing the Set Partitioning in hierarchical trees(SPIHT) image compression algorithm whichis wavelet based computationally very efficient, has low computational complexity, and generates an embedded compressed bit-stream that can be efficiently decoded at several data rates (qualities). And offers good compression ratios, fast execution time and good image quality.here we have given a detail working example of SPIHT for better understanding.
