Fundus image retina arteriosclerosis detection method based on improved encoding and decoding network
A fundus image, arteriosclerosis technology, applied in image enhancement, image analysis, image data processing and other directions, can solve the problem of less research on arterial blood vessels and arterial reflective strips segmentation, difficult segmentation of arterial blood vessels and arterial reflective strips, and arterial blood vessel segmentation. problems such as interference, to achieve the effect of enhancing target feature information, reducing interference, and improving network performance

[0021] The present invention will be further described in detail below in conjunction with specific embodiments.
[0022] The overall framework schematic diagram of the present invention is as figure 1 As shown, firstly, the fundus images diagnosed as retinal arteriosclerosis by ophthalmologists are collected, and a sampling line perpendicular to the arterial vessels and arterial reflective bands in the fundus image is collected. For the pixels on the sampling line, a four-segment Gaussian model is used to perform Fitting to obtain the gray distribution curve of the blood vessel cross-section, and then calculate the reflection parameter-bandwidth ratio and gray ratio to determine the quantitative detection threshold of retinal arteriosclerosis; The image database of the reflective tape, so the fundus images of the hospital are collected and the training samples are manually marked by ophthalmologists using the labeling tool; After the first feature extraction module, the resi...
