A New Contour Detection in Mammogram Using Sequential Edge Linking
A novel approach is presented to extract the contour of a region of interest (ROI) in mammogram. It combines the threshold segmentation method and sequential edge linking (SEL) algorithm. The salient area is located according to human visual characteristics, and then the optimal threshold is obtained and applied to the whole image. The binary image is processed by the SEL algorithm. Experiments show that the proposed method offers excellent ability to suppress noise and false edges. It can extract the precise and continuous contour of an ROI in mammogram.
