Abstract

The present invention relates to computer applying technology. The registration identifying system of the present invention consists of plate scanner with transparent medium adaptor, microcomputer with keyboard and display, laser printer electrically connected together via signal cables. The registration identifying process includes mainly adaptive enhancing of homolateral fundus vessel image; intersection point and pure node extraction of fundus vessel characteristic; normalization of fundus vessel characteristic nodes; and neighboring region registration and judgement of fundus vessel characteristic nodes. The computer-aided judgement means has light labor strength and other advantages.

Description

(1) Technical field: [0001] The invention relates to a computer-aided feature fitting recognition method of an ipsilateral fundus medical image, which belongs to computer application technology, and particularly relates to biomedical image processing and recognition technology. (two) background technology: [0002] Ophthalmology uses fundus cameras to take fundus photo images or negative film images during fundus clinical diagnosis or medical screening, and its archived data is gradually increasing. The left and right sides of the fundus image are different. To study or compare the follow-up photos or negatives in different periods, it is usually done manually now. The negatives need to be observed in a working environment with transmitted light. It is a very strenuous and complicated work, and the operators are labor-intensive, prone to fatigue, and inconvenient to unify and other troubles and burdens. (3) Contents of the invention: [0003] The purpose of the present in...
