METHOD AND APPARATUS FOR EVALUATING BLOOD VESSEL IN FUNDUS COLOR IMAGE, AND COMPUTER DEVICE AND MEDIUM

摘要

A method and apparatus for evaluating a blood vessel in a fundus color image, and a computer device and a medium. The method comprises: using a pre-trained segmentation model to extract a retinal blood vessel image of a topological structure from a fundus color image; extracting a blood vessel center line from the retinal blood vessel image, and setting an error band of the blood vessel center line by taking a preset standard blood vessel center line as a reference (S120); according to the error band, calculating an error of the blood vessel center line relative to the standard blood vessel center line, so as to obtain a blood vessel topological structure error of the retinal blood vessel image (S130); and according to the blood vessel topological structure error, evaluating the segmentation of the fundus color image by a segmentation model, and generating an evaluation result (S140), so that the blood vessel topological structure error is used for evaluating the integrity and accuracy of a blood vessel topological structure, and the evaluation effect is better.
