Driven by the tide of information and intelligence,the detection and classification of lesions under computer-aided endoscopy has shown high diagnostic accuracy, especially the emergence of deep learning and convolution neural network,which greatly promoted the development of intelligent endoscopy.The automated detection and diagnosis of colorectal polyps by artificial intelligence is a rapidly developing field in the field of artificial intelligence digestive endoscopy. In recent years, breakthrough research results in the field of intelligent detection of colorectal polyps have been emerging. This article reviews the research progress of computer-aided diagnosis and artificial intelligence in histological classification of colorectal polyps .
