Techniki usuwania szumów z obrazów oparte na transformacji falkowej i filtrowaniu przestrzennym staly się dośc standardowym narzędziem w wielu zastosowaniach i obszarach badań. Jednak poszukiwanie skutecznej techniki usuwania szumów z obrazów nadal stanowi wyzwanie. Niezależnie od tego, jak dobry aparat się używa, zawsze konieczna jest poprawa jakości obrazu, aby rozszerzyc zakres dzialania. Do tej pory wprowadzono wiele technik, ale większośc z nich opiera się na wlaściwościach przestrzennych obrazu lub wlaściwościach pikseli obrazu w wielu rozdzielczościach. W związku z tym zaproponowano ulepszony algorytm oparty na polączeniu cech obrazu w wielu rozdzielczościach i domenie przestrzennej. Metodologia opiera się na algorytmie opracowanym pierwotnie dla obrazów oglądanych lub przetwarzanych w wielu rozdzielczościach przy użyciu progowania falkowego, a następnie stosuje się techniki filtrowania przestrzennego w celu dalszej poprawy jakości obrazu. Algorytm usuwania szumów przewyższa standardowe techniki usuwania szumów pod względem kilku wskaźników ilościowych.
