Abstract :
This article presents multi-stage Computer Aided Design (CAD) processing to satisfy early detection of breast cancer. The most important feature within the breast region is the breast contour. Extraction of the breast region and delineation of the breast contour is an essential step in CAD. Primarily it allows the search for abnormalities to be limited to the region of the breast without undue influence from the background of the mammogram. A precise segmentation technique has been applied to suppress artifacts and accentuate the breast region, followed by a detection algorithm to classify the breast tissue region. To demonstrate the capability of the presented multi-stage CAD system it is extensively tested on mammograms from the Digital Database for Screening Mammography “DDSM” of the University of South Florida.
