A bit-plane data-reduction scheme based on some characteristics of human image perception is described. This scheme is on information lossy/modifying type. General properties of bit-plane-decomposed images are reviewed. A method that modifies less important portions on the bit-planes into flat areas, to achieve more uniform images, is introduced. A hierarchical algorithm for the purpose is presented as the actual strategy. The important features of this algorithm are that it can use the coded data in the depth first expression and that the data modification is not likely to affect edges and isolated small areas, which are both very important for image perception
