Abstract

The invention relates to a retina image classification method and device. The method comprises the following steps of: obtaining a sample retina image; extracting an interest area of the sample retina image and extracting an optic disk area and a blood vessel area in the interest area; extracting image features of areas except the optic disk area and the blood vessel area in the interest area so as to train an image classifier according to the image features; obtaining a to-be-classified target retina image; extracting a target interest area of the target retina image and extracting an optic disk area and a blood vessel area in the target interest area; and extracting image features of areas except the optic disk area and the blood vessel area in the target interest area so as to classify the target retina image according to the image classifier. The retina image classification method and device are capable of improving the efficiency and correctness of retina image classification, and is simple, practical and wide in application range.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for retinal image classification. Background technique [0002] The development of medicine is closely related to human health, so digital image processing technology has aroused strong interest in the biomedical community from the very beginning. As early as the end of the 1970s, literature statistics pointed out that a very wide application of image processing was medical image processing. In medicine, whether in basic subjects or clinical applications, it is an extremely diverse field of image processing. However, due to the difficulty of medical image processing technology, many processing are difficult to achieve clinical practicality. In recent years, with the decline of digital image processing equipment, the use of digital image processing technology to improve the quality of various medical images has reached the practical stage. [0003]...
