As a device for detecting colopathy, white light endoscopy still suffers from missed diagnoses and misdiagnoses. For increasing the diagnostic rate of colopathy sick persons, our work proposes a new diagnoses model for pathological changes based on an improved YOLOv5 algorithm based on the SwinTransformer framework. In this diagnostic model, colopathy is divided into three categories: polyp of the colon, adenoma of the colon, and carcinomas. The SwinStage structure, as well as the channel attention mechanism and spatial attention mechanism, are incorporated to fully extract features of the map and the relationship between feature maps, thereby improving the result of object detection. Experimental outcomes demonstrate that the proposed pathological tissue diagnoses model has a more excellent pathological tissue detection ability, the mAP@0.5 and mAP@0.5:0.95 can attain 0.915 and 0.717.
