1. A method for segmentation of fibro-glandular (FG) tissue, the method comprising: performing, by one or more processors, a training process, the training process comprising: estimating, by one or more processors, a preliminary FG region in a breast domain; extracting, by one or more processors, a set of global features from the breast domain and a set of specific features related to the preliminary FG region and non-FG regions; identifying, by one or more processors, a set of features for breast density discrimination; and configuring, by one or more processors, a fuzzy logic module, wherein the fuzzy logic module is based, in part, on a set of manual settings.
