Abstract
A suitable algorithm suggested with wavelet compression for gray scaleimages 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.
