Problems solved by technology

However, due to the influence of the actual environment, factors such as uneven background and unclosed edge lines of the captured original blood vessel images often have a great impact on the segmentation of blood vessel images, resulting in errors in the segmented blood vessel images, resulting in accurate blood vessel recognition. rate drop

Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0039] The segmentation method of blood vessel images provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the blood vessel image acquisition terminal 110 is connected to the computer device 120 through a wired communication line. The blood vessel image acquisition terminal 110 collects the blood vessel image under the microscope captured by the camera, and undergoes analog-to-digital conversion to obtain a transformed blood vessel image, and sends the transformed blood vessel image to the computer device 120; the ...

Abstract

The invention relates to a blood vessel image recognition method and device, computer equipment and a storage medium. The method comprises the steps of obtaining initial boundary pixel points based ongray values of pixel points in an initial blood vessel image; Constructing a threshold curved surface by taking the initial boundary pixel point as a boundary condition based on a preset stable temperature field model; Identifying the initial blood vessel image according to the threshold curved surface to obtain an identified blood vessel image; Carrying out binarization processing on the identified blood vessel image; And identifying a target area in the blood vessel image after binarization processing, and obtaining a target blood vessel image according to the target area. According to themethod, threshold curved surfaces with different thresholds are selected based on different regions; The blood vessel image is recognized, the defect that the blood vessel image recognized through a single threshold value is large in segmentation error is avoided, it is guaranteed that the edges of the recognized blood vessel image and the background image are clear, therefore, the recognition error is reduced, and the blood vessel recognition accuracy is further improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a recognition method, device, computer equipment and storage medium of a blood vessel image. Background technique [0002] In clinical diagnosis and treatment, blood vessels are very sensitive parts. Determining the location and parameters of blood vessels plays an important auxiliary role in clinical diagnosis and treatment. [0003] However, in order to segment the blood vessel image from the background, the traditional technology generally detects the discontinuity of the local features of the captured original blood vessel image, connects the detected discontinuous local features into edges, and divides the image through these edges. into different regions to segment blood vessel images from the background. However, due to the influence of the actual environment, factors such as uneven background and unclosed edge lines of the captured original blood vesse...
