Abstract
Conventional two-dimensional low-pass filtering of images for wideband noise suppression invariably, if not by definition, degrades the spatial definition of objects within the image. Thus, SNR improvement is achieved at the expense of edge fidelity. We present in this paper a technique which offers improved noise suppression relative to conventional filtering, and at the same time tends to preserve the important high frequency content of the target image.
