摘要：Image Compression is performing by wavelet packet transform. Wavelet packet transform is a transform function. This function can change data one form to another without any loss of information. In paper, we use block code speck for zero ordering tree. The value of PSNR (Peak Signal to Noise Ratio) is improved by the zero ordering trees, but same quality of degraded. Because on the time of zero ordering trees, values of MSE are changed, so the occurred bit pixel error raises the value of MSE. Through Self-Organized Mapped network (SOM), we maintain zero ordering trees and improved the PSNR value and image compression ratio.
