Abstract:
In this paper, the authors propose an algorithm for increasing the compression efficiency and visual quality during hierarchical compression. The algorithm is based on the use of pre-filtering that brings an image to a form that is more adapted to hierarchical compression. The developed algorithm was studied experimentally, the advantage of the scheme with pre-filtering over the basic method in terms of compression coefficient and visual quality was shown.

Keywords:
image compression, pre-filtering, hierarchical compression.
