Breast Boundary Detection in Mammogram using Entropy
Rahul Yadav Rajeshwar Dass · International Journal of Science and Research (IJSR) · 2012
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 Computer Assisted Diagnosis (CAD) systems. The Breast boundary region detection is a tough task because low contrast region near skin line(boundary). The proposed method is noise resistant and uses the concept of entropy estimation for breast boundary detection. The proposed algorithm was tested on 103 mammographic images taken from CityU Image Database of different profiles and visual results were evaluated by the expert.
