About
wavelet compression:
 Like
the traditional JPEG compression, wavelet
compression algorithm presents an image as
sets of real coefficients. Most of the
wavelet coefficients of a typical image are
nearly zero, and the image thus is
wellapproximated with a small number of
large wavelet coefficients
 The
advantage of wavelet compression is that, in
contrast to JPEG, wavelet algorithm does not
divide image into blocks, but analyzes the
whole image. The characteristic of the
wavelet compression allows to get higher
compression ratio for SOME images
