Abstract

The invention discloses a retina image analysis method applied to calculation equipment. The method comprises steps that a to-be-analyzed retina image is acquired, and the to-be-analyzed retina image is pre-processed to acquire an enhanced image; the enhanced image is filtered to extract a background image; a bright region image and a dark region image are determined according to RGB color values of pixels of the enhanced image and the background image; a videodisc region and a bright noise region are determined, and the videodisc region and the bright noise region are removed from the bright region image to acquire an exudation region; a blood vessel region and a dark noise region are determined, and the blood vessel region and the dark noise region are removed from the dark region image to acquire a hemorrhage region. The invention further discloses a retina image analysis device of the retina image analysis method, and the calculation equipment equipped with the retina image analysis device. The method is advantaged in that the exudation region and the hemorrhage region of the retina image can be rapidly acquired through segmentation.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a retinal image analysis method, device and computing equipment. Background technique [0002] Diabetes is a systemic metabolic disease. Long-term hyperglycemia will cause a series of chronic complications of diabetes, among which Diabetic Retinopathy (Diabetic Retonopathy, referred to as sugar net) is the most common eye complication. It can affect the patient's vision and even lead to blindness. Retinal hemorrhage and exudation lesions are one of the early visible signs of diabetic reticulum. Therefore, it is necessary to identify the hemorrhage area and exudation area on the retinal image through digital image processing technology. [0003] From the retinal image, because the hemorrhage is the product of microaneurysm rupture, it presents a gradual spreading trend clinically, so the color and shape of the hemorrhage area are similar to blood vessels, with ir...
