Image Compression Based On Wavelet Transtorm Improvenient Algorithm Of SPIHT

With the social development and extensive use of radio frequency resources become increasingly strained. In a variety of radio signals, the image data bandwidth maximum. Therefore, image data compression, on the conservation of radio frequency resource of great significance.This article introduced the principle of wavelet analysis and its application in mage compression coding application on the basis of a SPIHT algorithm. Standard SPIHT algorithm is the fundamental fact of the wavelet coefficients quantify the standard SPIHT algorithm to take a fixed binary range of quantitative, does not take the wavelet coefficients of energy distribution, and sometimes this approach is not necessarily the best. On this point this paper presents a new improved method. The algorithm than the standard SPIHT algorithm codec a significant reduction in the number of times, time consumption and PSNR and standards quite SPIHT algorithm. Finally, use MATLAB to realize that the process to improve the algorithm is reasonable.
