Colorectal polyp segmentation method based on endoscopic image

Abstract

The invention provides a colorectal polyp segmentation method based on an endoscopic image, which is used for determining a polyp specific area of polyp in colorectum from the endoscopic image of thecolorectum, and comprises the following steps: correcting and denoising the endoscopic image; selecting a polyp suspected region and a colorectal polyp clustering center point; setting an image analysis scale, and carrying out region enhancement on the suspected polyp region; selecting an initial background pixel clustering center point; taking the colorectal polyp clustering center point and theinitial background pixel clustering center point as initial clustering centers; establishing a cost function according to a k-means clustering method, and performing iterative computation on the initial clustering center so as to continuously update the current clustering center; obtaining a final clustering center until iteration is finished; and clustering the to-be-classified pixel points according to the final clustering center to obtain a specific polyp region. The method can accurately distinguish the edge area of the colorectal polyp and improve the segmentation precision of the colorectal polyp.

Description

technical field [0001] The invention belongs to the field of medical image processing, and relates to a colorectal polyp segmentation method, in particular to a colorectal polyp segmentation method based on an endoscope image. Background technique [0002] A polyp is an abnormal growth of tissue that is usually benign but can sometimes become cancerous. Colorectal polyps are formed on the lining of the colon or rectum. They are abnormal growths that start on the inner wall of the colon or rectum. A history of polyps is one of the main risks of colorectal cancer. Therefore, changes in the size of polyps cannot be ignored. The larger the size of the polyp, the The possibility of canceration is greater. [0003] Colonoscopy is a common clinical polyp detection method, which can detect precancerous polyps and cancer at the earliest stage of treatment. Doctors can remove early polyps or early lesions during the detection period to prevent the development of cancer. During this ...

Problems solved by technology

[0004] When determining the specific location of colorectal polyps in the colorectum, it is usually judged through the endoscopic image of the colorectum. It is difficult to distinguish, which makes it difficult to determine the specific area of ​​colorectal polyps, which in turn affects the segmentation accuracy of colorectal polyps
