Abstract

A gastrointestinal tract endoscope image preprocessing method including information screening and fusion repairing includes the steps that firstly, a key information extractor is used for extracting effective information areas in data set pictures twice, and the results of the two times of extraction complement each other and are stored as a new picture data set; brightness equalization and improvement are carried out on a new picture data set by using an improved EACE method, the overall brightness is improved while the defect of uneven brightness is improved, and more information beneficial to polyp identification is obtained; and light spot detection and light spot region repair are performed on the enhanced result by using a two-image matching fusion repair method. The interference of light spots in endoscope images on polyp detection results is reduced, and the misdiagnosis rate during polyp detection by doctors or computers is reduced.

Description

technical field

[0001] The invention relates to the field of gastrointestinal endoscope polyp detection, in particular to a gastrointestinal endoscope image preprocessing method combining information screening and fusion repair. Background technique

[0002] Digestive tract diseases and the canceration caused by their further deterioration are one of the killers of human health. According to related reports, three and four of the top five cancers in terms of morbidity and mortality in my country belong to digestive tract cancers, respectively. A polyp is a growth on the surface of the small intestine in the digestive tract. Most polyps are benign, but if they exceed 1 cm in size, they are more likely to become cancerous. Therefore, early detection and timely treatment of polyps can reduce the possibility of cancer in patients.

[0003] At present, most polyps are detected by gastrointestinal endoscopy. In one detection, the endoscope will collect a large number of gastroin...
