Wavelet analysis is most widely used in the field of modern communication business and information, we need to image processing. In order to effectively use the valuable resources of compress the image information. Due to the content of an image con- tains mainly concentrates in the low frequency part of the image, the image compression is realized by filtering the high frequency part of the image through wavelet technology. Wavelet packet is based on wavelet, which perfectly solves the problem that wavelet can＇t pick up the high frequency inf...
