Abstract
Digital mammograms are automatically segmented into background, corresponding to the region external of the breast, and foreground, corresponding to the region within the breast, by the detection of the skinline which forms a border between these regions. A binary array is produced representing an initial coarse segmentation between foreground and background in which a binary one value is assigned to each pixel in the binary array whose intensity exceeds an intensity threshold and/or whose gradient amplitude exceeds a gradient threshold.
