Semi Automatic Segmentation of Breast Cancer for Mammograms Based on Watershed Segmentation
نویسندگان
چکیده
Mammograms are the soft X-rays meant for the detection of any lesions or cysts in breasts. Nowadays it is playing major role in the detection of breast cancer at an early stage. In this paper we have developed a computer aided diagnosis tool using MATLAB for breast cancer in Mamograms. This segmentation technique is based on the extraction of catchments basins through a topographic representation of the mammography image. Applying the watershed algorithm on a rough image leads to over-segmentation problems. To avoid this, we have first carried out a preprocessing step. Then, we have found the distance transform of the prepossed image. Finally the watershed segmentation is applied to this latter image.

Introduction: Breast cancer is the most common cancer among women in the world. The automatic detection of masses in digital mammograms is a challenging task and a major step in the development of breast cancer CAD systems. In this study, we introduce a new method for automatic detection of suspicious mass candidate (SMC) regions in a mammogram. Methods: Mammography is widely used for the early...

Introduction Breast cancer is one of the most common types of cancer among women. Early detection of breast cancer is the key to reducing the associated mortality rate. The presence of microcalcifications clusters (MCCs) is one of the earliest signs of breast cancer. Due to poor imaging contrast of mammograms and noise contamination, radiologists may overlook some diagnostic signs, specially t...
