✦ Synopsis

This paper presents a new technique for image adaptive restoration called 3 -multiresolution plane "tting (3 -MPF) and the global restoration index (GRI) index, which evaluates the restoration performance of smoothing methods. The 3 -MPF "lter is based on an adaptive plane "tting technique using variable-sized windows with di!erent behavior for continuous regions or discontinuities. The criteria used to select the window size and detect discontinuities is the 3 -xdelity test. The GRI, integrates two independent indices measuring restoration smoothness and "delity. Using this index, the 3 -MPF "lter performance is compared with other traditional methods, demonstrating better performance under Gaussian noise and robustness against outliers.
