2 results about "Retinal vessel" patented technology

This invention discloses a method, apparatus, storage medium, and device for retinal vessel image segmentation, belonging to the field of image segmentation technology. The method includes acquiring retinal vessel images and inputting them into a trained retinal vessel segmentation model. Accurate segmentation of retinal vessels is achieved through newly introduced topological feature optimization and local and global feature optimization. This invention improves the modeling effect of vessel topology by introducing topological feature optimization into the encoder, and achieves accurate extraction of vessel details from different scales to the global level by introducing local and global feature optimization into the encoder, reducing the risk of vessel discontinuities and missed detections in the segmentation results.

This item is an image that displays information using a GUI. This GUI is an image that has the function of displaying the results of eye examinations in ophthalmology. Specifically, the image is divided into upper and lower sections, and the upper and lower sections display the results of the examination, such as a fundus photograph, a circular map showing the thickness of the retina, a cross-sectional image of the retina, and the reticular structure of the retina's blood vessels, respectively, and the image has the function of displaying the examination results in a way that allows comparison between the upper and lower sections. The roughly circular area on the left side of the image displays information related to the fundus photograph. The roughly square area on the left side of the center of the image displays information related to the circular map showing the thickness of the retina. Furthermore, the horizontal rectangle on the right side of the center of the image displays information related to the cross-sectional image of the retina. The roughly square area on the right side of the image displays information related to the reticular structure of the retina's blood vessels. When in use, it is displayed as shown in "Reference Figure 1 showing the usage state," and when it is a monochrome image in use, it becomes "Reference Figure 2 showing the usage state."
