Fuzzy image smoothing

摘要

A fuzzy model for a noisy image sequence is given, and thepossibility distribution function for an estimate of the original imageis deduced. An optimal estimate criterion, called the maximumpossibility criterion, is presented, and the fuzzy image smoothingalgorithm is derived. This algorithm can be realized by a simple digitalstructure with the desirable property of reduced memory requirements.For the average relative error, the algorithm performs better than theconventional average of multiple images algorithm with the distinctadvantage of suppressing noise in the case of a small number of images
