Abstract

The present disclosure relates to a method for repairing the optic disc area of ​​a fundus image and related products. The method includes: acquiring a first optic disc region image corresponding to a high-exposure fundus image and a second optic disc region image corresponding to a low-exposure fundus image; combining the second optic disc region image with the first optic disc region image performing image alignment to generate an aligned optic disc region image aligned with the first optic disc region image; determining a final optic disc region image based on the first optic disc region image and the aligned optic disc region image; and utilizing the final optic disc region Image restoration is performed on the image of the first optic disc region. Using the solution of the present disclosure, not only can effectively solve the problem of lack of information in the overexposed area of ​​the optic disc of the fundus image, but also preserve the true color of the fundus image.

Description

technical field [0001] The present disclosure generally relates to the field of image processing techniques. More specifically, the present disclosure relates to a method, an apparatus, and a computer-readable storage medium for inpainting an optic disc region of a fundus image. Background technique [0002] The optic disc (optic disc), which is called the optic disc, can also be called the optic nerve head. The optic disc is located approximately 3 millimeters ("mm") nasally from the macula to the retina, and is a well-defined, pale red disc-shaped structure approximately 1.5 mm in diameter. When collecting fundus retinal images, the optic disc area is often overexposed due to high reflectivity, and the overexposure of the optic disc will cause loss of information in the optic disc area of ​​the fundus image. The current mainstream image restoration and enhancement technology is High Dynamic Range Imaging ("HDR") technology, which can be used in digital image processing t...
