Detection of cancerous masses for screening mammography using discrete wavelet transform-based multiresolution Markov random field.

When cancerous masses are embedded in and camouflaged by varying densities of parenchymal tissue structures, they are difficult to visually detect on mammograms. We present a novel algorithm based on the discrete wavelet transform (DWT) and multiresolution markov random field (MMRF) that will single out the suspicious masses to assist the attending radiologist in making decisions.
