摘要：Wavelet anatomization is globally appreciated up to the sixtieth part of an hour tools for timefrequency. It acquires an exceptional development based on Fourier fractionation and plays a consequential character in the signal processing remarkably in image compression. By analyzing the relations of the coefficients between every main block and the complete image, we can locate the catalogue location of the sub-band of each son block in the same sub-band of the whole image is same as that of the son block in the origin image. Many image compression algorithms (lossy or lossless) have already been devised adhering to their perspective point of view. In this paper we propose conceptually an algorithm for image compression for minimizing a number of bits for storing an image into disk and reducing spatial redundancy and correlation between pixels.
