1. A method of producing spicule traces from digital mammogram images, comprising: selecting mass density candidates to obtain regions of interest (ROIs); pre-processing each mass density candidate to obtain a central mass segmentation and a corresponding spicules features map, wherein pre-processing each mass density candidate comprises: extracting a region of interest at each mass density segmentation candidate location; resampling the extracted region to a fixed dimension; enhancing the extracted region to produce an enhanced image; performing flood-fill segmentation on the enhanced image to search for a central mass segmentation; and applying an adaptive threshold to the enhanced image and an edge image to produce the spicules features map; and tracing the obtained central mass segmentations and associated spicules to produce the spicule traces.
