ANALYZER ANGIOGRAPHIC IMAGES OF THE HUMAN EYE

摘要

The technical result is the provision of automatic classification of the vascular bed and the ischemic zone in angiographic images of the human fundus. The fundus angiographic image analyzer includes, with the possibility of exchanging information and controlling, the input digital angiographic image input unit, the source image preprocessing unit, the vascular image analysis unit, the vascular extraction unit, the vascular ischemia zone allocation unit, and the memory unit. Contains a unit for determining the morphometric characteristics of vessels associated with the output of the vascular image analysis unit, including a module for calculating the area of the ischemic zone, a module for calculating the length of the vascular bed, a module for calculating the diameters of vessels, their mean value and standard deviation, as well as a module for calculating the density of the location of vessels, the output of the determination unit morphometric characteristics of vessels associated with the input of the classification block, which includes a module for determining the class of the image, the module for determining vascular weight, module for determining the class of the zone of ischemia, and the outputs of the unit for determining the morphometric characteristics of vessels and the classification unit are connected to the memory unit. 1 ill.
