Method of detecting and identifying lesions of gastrointestinal endoscope, based on sliding window

Abstract

The invention belongs to the technical field of intelligent processing of medical images, and specifically relates to a method of detecting and identifying lesions of a gastrointestinal endoscope, based on a sliding window. Early screening through endoscopy is an effective means of reducing the morbidity and mortality of cancers of the digestive tract. In traditional diagnostic methods, the diagnosis of a doctor is entirely a subjective judgment process, so that diagnosis is limited and influenced by the experience and knowledge level of the diagnostic doctor. Therefore, the method of detecting and identifying lesions of a gastrointestinal endoscope, based on a sliding window includes the steps: applying deep learning to lesion detection of a gastrointestinal endoscope, making a sample based on the frame of a lesion area marked by a doctor, and training a classifier; and proposing a candidate area in a gastrointestinal endoscope image to be detected, inputting the candidate area into the classifier, and performing post-processing on the classification result to achieve the purpose of lesion detection. The experiment result shows that the method of detecting and identifying lesionsof a gastrointestinal endoscope, based on a sliding window can accurately detect the lesion position of the gastrointestinal endoscope image so as to provide a reference for the doctor, thus showing that the artificial intelligence-assisted diagnosis and treatment of early digestive tract cancer has irreplaceable superiority.

Description

technical field [0001] The invention belongs to the technical field of medical image intelligent processing, and in particular relates to a method for detecting and identifying gastrointestinal endoscopic lesions based on a sliding window. Background technique [0002] Standardized gastrointestinal cancer screening, treatment, and follow-up are of great significance. Early cancer screening is an effective means to reduce cancer morbidity and mortality. The screening, treatment and follow-up of early gastrointestinal cancer mainly include endoscopy and postoperative CT examination, among which gastrointestinal endoscopy is the most important. In the traditional diagnosis method, the doctor's diagnosis is a process of subjective judgment, so it will be limited and affected by the experience and knowledge level of the diagnosing doctor; secondly, it is easy for the doctor to miss some subtle changes in the diagnosis; thirdly, the difference between different doctors and the sam...
