Abstract

Mammography helps to provide some criteria in order to help the physicians to decide whether a certain tumor is malignant or benign. A mammogram is an x-ray of the breast tissue which is designed such that it can approximately identify the abnormalities. In mammograms selection of suspected area is easy as it looks brighter than its surrounding pixels.The method used for detecting tumor in breast is based on edge based segmentation for which we are using Canny Edge Detection Technique. The work proposed is based on the following procedure: (a)Removing the background information (b)Applying the edge detection technique and retrieving the largest ROI (c)After getting the close loops, filling is performed inorder to highlight the tumor (d) Performing the morphological operations which are erosion and dilation. This method was tested over multiple images and implemented using matlab code.
