Embodiment Construction

[0061] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0062] In one embodiment, figure 1 A flowchart showing a method for identifying a macular region according to an embodiment of the present invention, the method comprising:

[0063] Step S11: acquiring a fundus image of the target object;

[0064] Step S12: Extract blood vessel information and optic disc information from the fundus image;

[0065] Step S13: using the blood vessel information and the optic disc information as input parameters of a regression model, to obtain the position information of the fovea output by the regression model;

[0066] Step S14: Determine the macular area of ​​the eye of ...

Abstract

Embodiments of the present invention provide a macular area recognition method, device, and computer-readable storage medium, wherein the method includes: acquiring a fundus image of a target object; extracting blood vessel information and optic disc information from the fundus image; The blood vessel information and the optic disc information are used as input parameters of the regression model, and the position information of the fovea output by the regression model is obtained; based on the position information of the fovea, the area of ​​the macular area of ​​the eye of the target object is determined location information. Solve the problem that the macular area cannot be accurately identified when the image quality of the macular area part is impaired.

Description

technical field [0001] The present invention relates to the technical field of medical image processing, in particular to a macular region recognition method, device and computer-readable storage medium. Background technique [0002] The macular area is located in the center of the retina and is the most sensitive area of ​​vision. The cone cells responsible for vision and color vision are distributed in this area. Therefore, any lesion involving the macula will cause a significant decrease in central vision, dark vision, and deformation. The macular area does not have a clear boundary, and the area extracted based on the fovea is called the macular area. [0003] At present, the extraction of the macular area generally adopts the following two solutions: using the image processing threshold method to locate the macular fovea due to the low brightness of the macular fovea, and then extracting the macular area; and, using morphology and feature extraction techniques to locate...
