| Abstract: | By using the wavelet, the wavelet-based multiresolution feature of image and the basic principles of image compression are introduced, and then the way to choose the types of analyzing wavelet in image processing is discussed. Moreover, three kinds of image processing methods such as EZW, SPIHT, and MRWD are analyzed and compared through experiment. |
