Abstract

The invention discloses a retina image preprocessing method, and the method is executed in the computing equipment. The method comprises the steps: obtaining a retina image which comprises a retina area and the background; cutting the retina image, wherein the cut image comprises a circular retina area; adjusting the size of the cut image into a pre-determined size; and carrying out the contrast enhancing of the image in the pre-determined size. In addition, the invention also discloses a retina image preprocessing device which can implement the above method, and the computing equipment which comprises the retina image preprocessing device. According to the technical scheme of the invention, the method can achieve the preprocessing of the retina image, so as to improve and unify the quality of retina images.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a retinal image preprocessing method, device and computing equipment. Background technique [0002] The retina is the inner layer of the eyeball wall, which is a transparent film that has the function of photosensitive imaging. Retinopathy (such as diabetic retinopathy, glaucoma, macular disease, etc.) can affect the vision of the patient, and even lead to blindness. Regular screening and early detection of retinopathy can minimize visual impairment in patients. [0003] At present, the commonly used method for detecting retinal lesions is fundus photography, that is, retinal images are first obtained by a fundus camera, and then the retinal images are analyzed to segment lesion areas. In order to improve the analysis efficiency and avoid misjudgment caused by analysts' inexperience or personal subjective cognition deviation, it is necessary to use digital imag...
