Abstract: Manual diagnosis of diseases is time-consuming, subjective and error prone. There is significant scarcity of medical experts in rural areas. Computer assisted diagnosis may help to overcome these challenges. Melanoma skin cancer may become fatal if not detected during its early stages. In the absence of experienced medical professionals, early diagnosis of melanoma may be attempted using machine learning. This paper proposes the melanoma skin cancer identification from dermoscopy skin images by exploring the ensembles of machine learning algorithms using amalgamation of TSBTC and BTC feature extraction methods with various colour spaces. Experimentations conducted with various colour spaces and machine learning algorithms with ensembles resulted in 432 variations of proposed technique. Considering the average of accuracy, sensitivity and specificity; ensemble of AD tree-random forest-SVM in YCbCr colour space with TSBTC features performs best, followed by ensemble of random tree-random forest-AD Tree-SVM in LUV colour space with TSBTC features.

Keywords: dermoscopy skin images; melanoma; machine learning; feature extraction; colour spaces; ensemble; TSBTC; LUV.
