Deep learning intestinal tract polyp segmentation method based on multi-scale information and parallel attention mechanism

Abstract

The invention discloses a deep learning intestinal polyp segmentation method based on multi-scale information and a parallel attention mechanism, and the method comprises the steps: extracting features from finer granularity in a mode of building a branch during coding, and recalibrating a feature response through an improved compression excitation module; on the basis of pooling of the cavity space pyramid, further extracting and fusing features by establishing the relation between branches, multi-scale features of the intestinal tract and the polyp can be more accurately extracted and distinguished, so the problem that wrinkles of the intestinal tract wall are often misjudged as a polyp area during segmentation is well solved; during decoding, abandoning shallow features, refining the deep features, and further establishing a boundary relationship by using an attention mechanism, so a polyp boundary can be segmented more accurately on the basis of shortening training time.

Description

technical field [0001] The invention relates to the field of deep learning image segmentation, in particular to a deep learning intestinal polyp segmentation method based on multi-scale information and parallel attention mechanism. Background technique [0002] Gastrointestinal diseases are the most common human diseases, seriously affecting human life and health. According to statistics, among gastrointestinal diseases, colorectal cancer is the third most common cancer in the world after lung cancer and breast cancer, and intestinal polyps, as a high-risk precancerous disease, are the predecessor of colorectal cancer. Therefore, the prevention of colorectal cancer by detection and removal of preneoplastic polyps is crucial and a worldwide public health priority. Currently, colonoscopy is the "gold standard" technique for diagnosing colorectal adenomas and cancers. In my country, the annual demand for gastrointestinal endoscopy is more than 100 million, and it is widely us...
