Noise reduction on mammographic phantom images [PDF]
ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2006 A noise reduction scheme on digitized mammographic phantom images is presented. This algorithm is based on a direct contrast modification method with an optimal function, obtained by using the mean squared error as a criterion. Computer simulated images containing objects similar to those observed in the phantom are built to evaluate the performance of
