摘要: A method, computer readable medium, and device for reducing speckle in an image by detecting the edges of to create edge detected image, binarizing a binary processing, creating list, L, connected components C, list L that are smaller than predetermined number pixels, determining noise candidate pixels from covered computing histogram h e calculating threshold total marking C having pixel intensity as noise. The marked may then be removed setting background color image. Optionally, M N counted percentage p candidates is calculated p=M/N. processing only removes if more stops less percentage.
