Skin Lesions Identification Using Deep Convolutional Neural Network

TLDR: This paper proposes a 5-layer Convolutional Neural Network for classifying skin lesions of three categories, including melanoma belonging to deadly skin cancer, and achieves almost 95% accuracy, 94% sensitivity, 97% specificity, and 100% AUC on the test set.

Abstract: Skin cancer is a serious public health problem due to its increasing incidence and subsequent high mortality rate. Deep learning is one of the most important approaches in image analysis used to detect melanoma skin cancer. In this paper, we propose a 5-layer Convolutional Neural Network (CNN) for classifying skin lesions of three categories, including melanoma belonging to deadly skin cancer. The CNN based classifier trained and tested on the PH2 dataset of Dermoscopic images, which is developed for research and benchmarking purposes. The proposed model was evaluated by four well-known performance measures namely, classification accuracy, sensitivity, specificity and area under the curve (AUC). It achieved almost 95% accuracy, 94% sensitivity, 97% specificity, and 100% AUC on the test set. Moreover, in one case of the experiment, the proposed model achieved 100% accuracy.
