Abstract

The invention provides a gastric mucosa image boundary quantification method and device, a terminal and a storage medium. The method comprises the following steps: acquiring a microstructure segmentation image and a capillary segmentation image corresponding to a gastric mucosa dyed and amplified image; superposing the microstructure segmentation image and the capillary segmentation image to obtain a gastric mucosa superposition image; traversing pixel points on the gastric mucosa superposition graph according to a preset sequence, and obtaining coordinate information corresponding to the pixel points on the gastric mucosa superposition graph; identifying the distribution type of the microstructure in the microstructure segmentation map to obtain the distribution type of the microstructure; on the basis of the distribution type of the microstructure and the coordinate information corresponding to the pixel points, whether boundary points meeting preset requirements exist in the pixel points on the gastric mucosa superposition graph or not is judged, and a boundary point judgment result is obtained; and based on a boundary point judgment result, performing boundary quantization on the gastric mucosa dyeing magnified image. According to the embodiment of the invention, the quantization accuracy of the gastric mucosa boundary is improved.

Description

technical field [0001] The present application relates to the field of medical assistance technology, in particular to a method, device, terminal and computer-readable storage medium for quantifying the boundaries of gastric mucosal images. Background technique [0002] The root cause of gastric cancer endangering human health is that it cannot be detected early. Digestive endoscopy is the most commonly used and powerful method for screening and diagnosing early-stage tumors in the digestive tract. The advent of chromoendoscopy has established an endoscopic diagnosis method for early-stage gastric cancer. [0003] Yao Kenji pointed out in his V·S classification theory that endoscopic examination of early gastric cancer is characterized by the existence of a clear dividing line between cancerous and non-cancerous mucosa, and the presence of irregular microvascular structures within the dividing line (microvascular, MV) and / or irregular MS micromorphological structure (micros...
