Problems solved by technology

However, the non-mydriatic fundus camera is easy to operate and does not require professional doctors or nurses to operate, and the screening of diabetic retinopathy is usually not carried out in hospitals. There are a series of situations that lead to unqualified fundus image quality, such as operational errors, problems with the fundus camera itself, and blurred images caused by the patient’s lack of cooperation. Delay in patient treatment

Embodiment Construction

[0046] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0047] The invention provides a method for detecting the image quality of diabetic retina based on image analysis technology, the method comprising:

[0048] S1. Receive the color fundus image sent by the camera device;

[0049] S2. Perform preprocessing on the color fundus image, and select a G-channel grayscale image that preserves important physiological structures and lesions;

[0050] S3. Perform morphological processing, equalization processing, and / or filtering processing on the G-channel grayscale image to obtain a processed grayscale image;

[0051] S4. Perform brightness detection, video disk detection and definition detection on the processed grayscale image in sequence;

[0052] S5 , performing a diagnosis of diabetic retinopathy on the image afte...

Abstract

The invention relates to the technical field of image processing, in particular to a diabetic retina image quality detection method based on an image analysis technology. The method comprises the following steps of: preprocessing the fundus image, performing morphological treatment, equalization treatment and filtering treatment on the fundus image during the pretreatment process, performing brightness detection, optic disc detection and definition detection after the pretreatment, and finally obtaining the fundus image to be diagnosed, and diagnosing diabetic retinopathy. The preprocessing operation in the method greatly improves the visibility of the retinal fundus image, It is more advantageous for doctors to diagnose and analyze the patients' condition, and the quality inspection operation can greatly reduce the occurrence of the unqualified fundus images taken at the census spots. The fundus images which pass the quality inspection can be used for the preliminary diagnosis of diabetic retinopathy.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image quality detection method for diabetic retina based on image analysis technology. Background technique [0002] Diabetic retinopathy is one of the most serious complications of diabetes. It not only causes irreversible damage to the retina, but also can lead to vision loss or even blindness without timely drug treatment. At present, the number of diabetic patients in my country is about 110 million, accounting for about a quarter of the total population of diabetic patients in the world, and among these 110 million diabetic patients, there are 50 million patients who may develop diabetic retinopathy Therefore, for patients with diabetic retinopathy, early detection and early treatment have become the only way to suppress blindness due to diabetic retinopathy. [0003] With the popularization of diabetic retinopathy screening and the improvement of census efficien...
