Embodiment 1

[0023] According to an embodiment of the present invention, a method embodiment of a method for segmenting retinal blood vessels in a fundus image is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be performed on a computer such as a set of computer-executable instructions system, and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0024] figure 1 is a method for segmenting retinal blood vessels in fundus images according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0025] Step S102, acquiring a fundus image.

[0026] Specifically, the fundus image may be obtained by taking a photo.

[0027] In step S104, the fundus image is processed based on the Hessian matrix to obtain a first retinal blood vessel map.

[0028] Specifically, ...

Embodiment 2

[0072] According to an embodiment of the present invention, a product embodiment of a device for segmenting retinal blood vessels in a fundus image is provided, Figure 4 is a device for segmenting retinal blood vessels in fundus images according to an embodiment of the present invention, such as Figure 4 As shown, the device includes an acquisition module 101 , a first processing module 103 , a second processing module 105 and a reconstruction module 107 .

[0073] Among them, the acquisition module 101 is used to acquire the fundus image; the first processing module 103 is used to process the fundus image based on the Hessian matrix to obtain the first retinal blood vessel map; the second processing module 105 is used to analyze the first retinal blood vessel The image is binarized to obtain a second retinal vessel map; the reconstruction module 107 is configured to reconstruct interrupted vessels in the second retinal vessel map to obtain a third retinal vessel map.

Abstract

The invention discloses a method and a device of segmenting retinal vessels in a fundus image. The method comprises steps that the fundus image is acquired; the fundus image is processed based on a Hessian Matrix to acquire a first retinal vessel image; the binarization processing of the first retinal vessel image is carried out to acquire a second retinal vessel image; broken vessels in the second retinal vessel image are reconstructed to acquire a third retinal vessel image. The technical problems of the prior art such as high complexity and inaccurate segmentation results during the segmentation of the retinal vessels in the fundus image are solved.

Description

technical field [0001] The invention relates to the field of computer internet, in particular to a method and device for segmenting retinal blood vessels in fundus images. Background technique [0002] Among the various information that humans receive from the outside world, more than 80% of the information comes from vision. Therefore, the eyes are the most important sensory organs of the human body. The optic nerve of the fundus is the part of the brain that extends outwards and is an important visual organ. Diseases of the fundus often cause vision loss or permanent loss. In addition, fundus changes caused by fundus circulatory disorders and systemic diseases can be manifested in the retina and choroid to varying degrees. Therefore, the processing of fundus photos can provide early diagnosis or prognosis judgment function for some systemic diseases. [0003] The traditional method of fundus examination relies on fundus photos and the observation and analysis of doctors...
