Topic : “Development of Computer Aided Diagnosis System (CADx) for Detection of Anomalies in Breast using Textural Features with PNN classifier”

Authors:Miss. Ankita Satyendra Singh || Mrs. M. M. Pawar

Abstract:High False Negative Rate (FNR) is a very significant problem in a Computer Aided Diagnostic System as false negative answer may lead to a very high increase in the number of deaths. The main aim of this paper lies in the development of a new Computer Aided Diagnosis (CADx) system for the proper identification of breast masses. It also focuses at extraction of textural features. The input images are pre-processed by using Adaptive Median Filter and then segmented by using Gaussian Mixture Model i.e. GMM segmentation and further are subjected to feature extraction, selection and finally classification by using PNN classifier. MIAS database is used for research purpose which contains 322 mammogram images out of which 60 images as 20 of benign, 20 malignant and 20 normal are taken into consideration for feature extraction. 22 texture features are extracted and are further classified. PNN classifier with 80-20 train-test partition is used for classification. The Sensitivity, Specificity and Accuracy obtained by the selected features are 100%, 100%, and 100% respectively. .

Keywords: Mammogram, Pre-processing, Adaptive Median Filter , Gaussian Mixture Model (GMM), EM algorithm, MAP algorithm, Image segmentation, Texture features, Classification, PNN classifier
