Exponentially weighted and heaped Multilayer perceptron for skin Cancer diagnosis using multi Directional systems

Abstract

Skin cancer is the most dangerous and deadliest disease and its incidence and mortality rate increases worldwide. The analysis of dermoscopic images is the most appropriate non-invasive method for skin cancer diagnosis as a large amount of diagnostic information can be gleaned from dermoscopic images. Though many existing algorithms available for feature extraction and classification for a particular medical image classification system, the main aim of study is to improve the accuracy of the skin cancer classification system. The selection of features and classifiers can greatly improve the accuracy of diagnosis and reduces the computation time. This research work aims to build an effective dermoscopic image classification system to diagnose skin cancer at the earliest. To achieve this goal, a Hybrid Artificial Intelligence Model (HAIM) is developed for dermoscopic image classification that combines different multi-directional representation systems with an efficient Exponentially Weighted and Heaped MultiLayer Perceptron (EWHMLP) for the successful classification. newlineAt first, the use of texture analysisis explored by the use of frequency domain analyzes to find out if the dermoscopic images can be classified from texture. Among the transformations techniques, Wavelets is a multiresolution analysis and Curvelet, Contourlet and Shearlet are the multidirectional analyzes. The proposed system has two stages; information or feature extraction from the dermoscopic images and then classification. Features which are discriminate in nature are extracted using different transformation in the former process and they are classified in the later stageusing the classifier. newline
