A Novel Approach towards Segmentation of Breast Tumors from Screening Mammograms for Efficient Decision Support System

This paper presents a novel approach to finding a priori interesting regions in mammograms. In order to delineate those regions of interest (ROI’s) in mammograms, which appear to be prominent, a topographic representation called the iso-level contour map consisting of iso-level contours at multiple intensity levels and region segmentation based-thresholding have been proposed. The simulation results indicate that the computed boundary gives the detection rate of 99.5% accuracy. Keywords—Breast Cancer, Mammogram, and Segmentation.
