By analyzing the dermoscopy pictures, a unique technique is developed for classifying melanocytic tumors as benign or malignant. The algorithm contains the following steps: first, lesions extracted using k-means method; then second, features are extracted; and third, lesion classification by using a classifier based on a Support Vector Machine (SVM) model. Lesions occur that are overlarge to be entirely contained among the dermoscopy image. To influence this tough presentation, new features are proposed, and which are able to characterize border irregularities on both complete and incomplete lesions. In this model, to achieve improved performance a SVM classifier is intended. Experiments are administered on two numerous dermoscopy databases that embrace images of both the xanthous and caucasian races. The results show that classification accuracy is greatly enhanced by the employment of the new features and also the proposed classifier model.
