ABSTRACT

Title : Image Segmentation using Extended Edge Operator for Mammographic Images
Authors : Dr. H. B. Kekre, Ms. Saylee M. Gharge
Keywords : mammographic images,segmentation,edge operator .
Issue Date : July 2010
Abstract :
Detection of edges in an image is a very important step towards understanding image features. Since edges often occur at image locations representing object boundaries, edge detection is extensively used in image segmentation when images are divided into areas corresponding to different objects. This can be used specifically for enhancing the tumor area in mammographic images. In this paper extended Sobel , Prewitt and Kirsch edge operators are proposed for image segmentation of mammographic images. Edges and tumor location can be seen clearly by using this method. For comparison purpose Gray level co-occurrence matrix, watershed algorithm, present Sobel, Prewitt and Kirsch edge operators are used and their results are displayed.
