代码说明：

A suitable algorithm suggested with wavelet compression for gray scale images based on one- and two-dimension combined hierarchical structure, in the sub-band which has been generated by the aid of several types of wavelet functions. It is shown that the using of combined based hierarchical structures allows us to reduce the calculations complexity of compression and decompression at constant values of compression coefficients
