Abstract

The invention provides a method for carrying out processing on a meibomian gland image to obtain gland information. The method comprises the following steps: obtaining a meibomian gland image, and manually sketching a gland region and a meibomian gland region in the meibomian gland image; through an image Convolution-Highlight Detail operator, enhancing the outline of the glands and distinguishing glands and eyelids; through an image Threshold operator, adjusting parameter values and extracting the glands; through a morphology operator, further distinguishing the glands to enable the glands to be segmented clearly, and calculating the area of the central gland; and manually sketching the length of the central gland and automatically calculating the average length of the glands, and thus gland information is obtained. The method can carry out quantitative analysis on the meibomian gland images, and accurately calculate the information of deletion percentage and the central gland mean value and the like; and meanwhile, the method can accurately distinguish the glands, thereby providing accurate data for users and furthermore, providing scientific basis for MGD clinical diagnosis.

Description

technical field [0001] The invention relates to the field of image processing, and more specifically, relates to a method for processing meibomian gland images to obtain gland parameter information. Background technique [0002] In 1982, Gutgesell et al first proposed the concept of meibomian gland dysfunction (MGD). In domestic monographs on ophthalmology, the disease of meibomian gland dysfunction has also been mentioned long ago. With the publication of a series of reviews on MGD by the International MGD Working Group, the relationship between MGD and dry eye has been further understood, and the articles on basic and clinical research on MGD have also increased year by year. MGD is the main cause of evaporative dry eye. is the general consensus. Blepharitis and MGD are two independent diseases, but closely related to each other. MGD is one of the main causes of posterior blepharitis, and posterior blepharitis will directly or indirectly affect the structure of the meib...
