Performance Analysis of Wavelet Packet Based SPHIT Algorithm
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 2
Abstract
The necessity in image compression continuously grows during the last decade. An image compression algorithm based on wavelet packet transform is introduced. This paper introduces an implementation of wavelet packet image compression which is combined with SPIHT (Set Partitioning in Hierarchical Trees) compression scheme. The image compression includes transform of image, quantization and encoding. This paper describes the new approach to construct the best tree on the basis of Huffman coding for further compression. In this method the tree are known as zero trees and they are efficiently represented by separating the root from the tree to make compression more. Through Experiments (SPIHT Algorithm)we have shown that the image through the wavelet transforms, the wavelet coefficients are generally small value in high frequency region. A large number of experimental results are shown that this method saves a lot of bits in transmission, further enhanced the compression performance.
