In this paper we present the novel technique for detection of breast boundary (also known as Breast contour, breast edge, skin-air interface or also called skin-line). Breast boundary extraction is an important preprocessing step in CAD systems. The Breast boundary region detection is a tough task because low contrast region near skin line (boundary). The proposed method uses the concept of entropy estimation of breast boundary detection. The proposed algorithm is also noise resistant (i. e there is no need to filter the image before algorithm). The algorithm was tested on 103 mammographic images of different profiles and result was evaluated by an radiologist. The mammographic images were taken from CityU Image Database.
