Abstract: Medical computer science is the study that integrates two kinds of medical information: biological data and imagery. Medical picture data consists of pixels, which relate to a physical item and are generated through imagery. In order to get their insight value, analysis, and diagnosis of a particular condition, exploration of medical image data approaches is a problem. Image classification plays an essential part in the diagnosis of the computer and is a major barrier to the study of images. This task was connected to the use of methodologies and techniques in the use and validation of picture classification to get knowledge of the medical expertise, the results of patterns identification and classification methods. . The major goal of categorizing medical pictures is not merely the attainment of high accuracy but also the identification of which parts of the human body are afflicted by the disease. This article discusses the state-of-the-art approaches in the categorization of images to detect human body illnesses. The paper examined techniques to categorize medical pictures utilizing photographs, datasets, and methodological exchange.Keywords— classification technique, Medical imaging, Nearest Neighbor Network, Artificial Neural s, SVM.
