Dermatologist-Level Classification of Skin Cancer Using Cascaded Ensembling of Convolutional Neural Network

Skin cancer is a typical frequent malignancy that is typically identified visually after an initial screening, dermoscopic analysis, a biopsy, and histological investigation. Using photographs to automatically classify skin lesions is a difficult task, but convolutional neural networks (CNN) have the capacity to perform a wide range of broad and highly variable tasks across many fine-grained object categories. Malignant melanoma, often known as melanoma, is the deadliest type of skin cancer and is to blame for 75 percentage of skin cancer-related deaths while being the least frequent type. Deep learning methods were employed by the suggested system to recognize melanoma. The proposed approach, which makes use of clinical photos, could help a dermatologist identify this sort of skin cancer early on. Here, the input photos undergo pre-processing to lessen any lighting and noise artefacts that may be present. The pre-trained CNN then uses the improved images to identify which is malignant and which is benign .

I. Introduction

MALIGNANT melanoma, usually referred to as melanoma, is a form of skin cancer that arises from melanocytes, or cells that produce color. Melanomas frequently develop in the skin, although they very rarely do so in the mouth, gut, or eye. It is, regrettably, the most lethal variety of skin cancer. According to the 2015 analytical report, 3.1 million persons had active disease, which led to 59800 fatalities. Dermatologists currently examine every patient’s mole from the point of diagnosis to find "ugly ducklings" or outlier lesions that could turn into melanoma. This is quite a tedious and arduous task, as you might expect. Deep learning-based efforts to create algorithms to aid dermatologists in disease diagnosis have been made in recent years.
