Abstract: This study deals with a novel approach for the development of a Computer Aided Diagnosis (CAD) system for mammogram image analysis. Now a days a CAD system is playing vital role in the visual inspection of mammogram images and for the detection of breast cancer at an early stage.Here the authors have made an attempt to implement a CAD system for the detection of microcalcifications from a mammogram image segmentation and analysis. The system is implemented over a PC with the most common environment and also the algorithm used is easy and simple for any radiologist to take clear decision
