Abstract

The invention discloses a nuclear cataract recognition method and device, electronic equipment and a storage medium, and belongs to the technical field of artificial intelligence. The method comprises the following steps: extracting region features of a crystalline lens nuclear region in a sample eye image, extracting shape features of the crystalline lens nuclear region in the sample eye image, and determining target features of the sample eye image according to the region features and the shape features; and based on the target features of the sample eye image, constructing a nuclear cataract recognition model for determining the nuclear cataract level of the to-be-recognized eye image. According to the technical scheme, the lesion features of the crystalline lens nuclear region in the fundus image can be accurately obtained, so that the judgment of the nuclear cataract level is more accurate, a new thought is provided for automatic diagnosis of the nuclear cataract, and an ophthalmologist can be assisted to efficiently, objectively and accurately diagnose the nuclear cataract.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of artificial intelligence, in particular to the technical field of image processing, and in particular to a nuclear cataract identification method, device, electronic equipment, and storage medium. Background technique [0002] Nuclear cataract is a major blinding and vision-impairing ophthalmic disease. The clinical symptoms are cloudy and gradually hardening and darkening in the nuclear area of ​​the lens. Early intervention and cataract surgery can effectively improve the vision and quality of life of cataract patients. Anterior segment optical coherence tomography (AS-OCT) is a kind of optical coherence tomography (OCT). AS-OCT images have the characteristics of non-contact, high detection sensitivity, fast, high resolution, fast inspection, objective and quantitative measurement, and can obtain the entire lens structure. [0003] In basic clinical research, scholars have studied...
