A Fast Algorithm of Image Layer-Presentation

A new algorithm of image layer-presentation was proposed. The key concept of the algorithm was in that the image grayscale function f(x,y), which was comparatively irregular, was approximated by a series of high-regular grayscale functions g_n(x,y). The algorithm had the feature of fast convergence and so it was a good approximator. Due to its high-regularity, g_n might be stored in a quite small memory space. Thus, the algorithm gives a new way for data processing and image reconstruction.
