Automatic focus retaining method for upper gastrointestinal endoscopic image

Abstract

The invention discloses an automatic focus retaining method for an upper digestive tract endoscopic image. The method comprises the following steps: collecting and preprocessing digestive tract data; a large part classification model M-Net is constructed; a focus detection model is constructed to carry out focus detection on the large parts; constructing a focus separation and induction device, numbering the input pictures according to focuses, and respectively inducing the input pictures into different folders; constructing a mucous membrane visualization model, and removing invalid pictures or artifact pictures with poor visualization degree; constructing a 26-part positioning model, and performing 26-part classification on the upper digestive tract; and automatically outputting a picture reserving result. According to the method, the high-quality picture of the abnormal lesion of the upper digestive tract can be automatically reserved finally, and the specific part can be quickly positioned. According to the method, an endoscopic physician can be helped to quickly and automatically position and retain images of abnormal focuses of the upper digestive tract, the integrity and effectiveness of the images reserved by an endoscopic report are well improved, the homogenization of the comprehensive quality of the endoscopic report is realized, and the guidance treatment value and follow-up visit value of the endoscopic report are consolidated.

Description

technical field [0001] The invention relates to the field of medical assistance technology, in particular to a method for automatically retaining images of lesions for upper gastrointestinal endoscopic images. Background technique [0002] Endoscopy report is a widely used form of medical graphic report, and it is an intuitive and complete summary document of digestive endoscopy that is convenient for patients to store and easy for doctors to review. The endoscopy report is the objective basis for the diagnosis and follow-up of the disease, consultation and communication, medical appraisal and other scenarios. [0003] During the upper gastrointestinal endoscopy, the endoscopist can record the inspection findings by pressing the "picture collection" button or stepping on the "picture collection" pedal, and all the collected pictures are saved in the image gallery in the document workstation. The endoscopist consults and reviews the library of acquired images to form a fina...
