Retrieval in Dermatology using Intelligent Techniques

Abstract

Identification of skin disease has become a challenging task with the origination of various skin diseases. The architecture used in this work is content-based image retrieval to facilitate medical diagnosis. In this work, analysis of feature vectors based on fusion of colour and texture and shape features are carried out. The feature vector data are fed into an optimization framework. The results proved that using precision recall curve the shape feature vectors and Mahalanobis distance measure have high contribution to computer-aided diagnosis of skin lesions. Experiments on a set of 2420 images yielded a specificity of 97.04% and a sensitivity of 80.81%. Our empirical evaluation has a superior retrieval and diagnosis performance when compared to the performance of other works. The work is tested with 40 skin diseases.

Ganasigamony W. Jiji is a professor of computer science and engineering at Dr. Sivanthi Aditanar College of Engineering, Tiruchendur. She has published more than 72 scientific research papers. She is a recipient of 10 national and two state awards. Her long-term research focuses on Computer-Aided Detection (CAD) and Measurement (CAM) of lesions in medical images. CAD research aims at discovering the fundamental perception processes of human vision in the image-based diagnosis of lesions, and developing mathematical/computational models that describes them. Her area of interests is computer-aided detection and diagnosis of abnormality using medical images and medical image analysis suchasimage enhancement, segmentation, feature extraction, object detection and pattern recognition.
