Adversarial network generation method and fundus fluorescence contrast image non-perfusion area segmentation method

Abstract

The invention discloses an adversarial network generation method and a fundus fluorescence contrast image non-perfusion area segmentation method, and relates to the technical field of image processing, and the method comprises: obtaining a sample fundus fluorescence contrast image; inputting the sample fundus fluorescence contrast image into a generator to obtain an output segmentation result; inputting the output segmentation result and a real segmentation result corresponding to the sample fundus fluorescence contrast image into a discriminator to obtain a discrimination result, and forming an adversarial network by the generator and the discriminator; and training the generator and the discriminator according to the output segmentation result, the real segmentation result and the discrimination result, wherein the trained generator is used for segmenting the target fundus fluorescence contrast image. The effect of quickly and accurately segmenting the non-perfusion area of the fundus fluorescence contrast image through the neural network is achieved.

Description

technical field [0001] The invention relates to a method for generating an adversarial network and a method for segmenting non-perfusion areas of fundus fluorescein contrast images, and belongs to the technical field of image processing. Background technique [0002] Retinal capillary non-perfusion (Capillary Non-Perfusion, CNP) is one of diabetic retinal vascular lesions. Due to the complete occlusion of capillaries, blood stops flowing to certain areas of the retina, resulting in the generation of non-perfusion areas. In the non-perfused area of ​​the retina, the fundus macula is in a state of ischemia and insufficient oxygen, and new blood vessels are prone to form near the non-perfused area. Because the permeability of the tube wall of the new blood vessels is extremely unstable, exudation and bleeding are prone to occur, resulting in the entire Vitreous hemorrhage can lead to blindness in severe cases. CNP is also present in cerebral malaria, causing impaired retinal p...

In the non-perfused area of ​​the retina, the fundus macula is in a state of ischemia and insufficient oxygen, and new blood vessels are prone to form near the non-perfused area. Because the permeability of the tube wall of the new blood vessels is extremely unstable, exudation and bleeding are prone to occur, resulting in the entire Vitreous hemorrhage, which can lead to blindness in severe cases

CNP is also present in cerebral malaria, causing impaired retinal perfusion due to sequestration of parasitic erythrocytes in retinal vessels
