Early detection of skin cancer is crucial for successful treatment and improved patient outcomes. The most prevalent form of cancer is skin cancer and if left undetected, it can spread and become more difficult to treat. A dangerous and frequently fatal type of skin cancer is melanoma. Regular skin examinations and self-examinations can help identify suspicious moles or lesions, which can then be evaluated by a dermatologist. In addition, advances in technology and artificial intelligence have enabled the development of tools for automated skin cancer screening, providing a convenient and efficient means of early detection. This can lead to more efficient diagnosis, reduced healthcare costs and improved patient care. By evaluating skin lesions from images, deep learning techniques have shown considerable potential in increasing the precision of melanoma detection. By using large datasets and complex neural networks, deep learning algorithms can effectively distinguish between benign and malignant skin lesions with high accuracy. Ensemble of CNN models helps improve the performance and reliability of the classification task. By combining the predictions of multiple CNN models lead to more accurate and robust predictions. In this thesis, for melanoma classification problem, many different data augmentations techniques applied and different convolutional neural networks architectures evaluated, applied vignetting effect filter and hair noise in accordance with the dataset and results of ensemble of the best CNN models are promising. This thesis attempts to produce a reliable model for the classification of melanoma by conducting experiments on two combined publically accessible data sets, ISIC 2019 and ISIC 2020. On the testing sets in our studies, the proposed solution attained 95.75% AUC.
