Abstract
Disclosed herein are a glaucoma diagnosis method using a fundus image and an apparatus for the same. The glaucoma diagnosis method includes performing data amplification of generating multiple transformed images for an original fundus image based on a preprocessed image of the original fundus image, allowing multiple individual learning models of different types to be learned based on the multiple transformed images and generating a glaucoma determination model based on respective outputs of the learned multiple individual learning models, and diagnosing a class of glaucoma for the original fundus image based on the glaucoma determination model.
Claims16
A glaucoma diagnosis method, comprising:
- performing data amplification of generating multiple transformed images for an original fundus image based on a preprocessed image of the original fundus image;
- allowing multiple individual learning models of different types to be learned based on the multiple transformed images and generating a glaucoma determination model based on respective outputs of the learned multiple individual learning models;
- and
- diagnosing a class of glaucoma for the original fundus image based on the glaucoma determination model,
- wherein performing the data amplification comprises designating multiple capture areas for generating the multiple transformed images within a range preset based on an optic disc detected from the preprocessed image,
- wherein each of the multiple capture areas has a shape of a square, having sides of a preset length, in consideration of a size of the optic disc and has a center of gravity thereof located on a circumference of a virtual circle having a center of the optic disc as a center of the virtual circle, wherein a radius of the virtual circle is greater than that of a circle corresponding to a boundary of the optic disc.
A glaucoma diagnosis apparatus, comprising:
- a preprocessing unit for generating a preprocessed image of an original fundus image;
- a data amplification unit for generating multiple transformed images for the original fundus image based on the preprocessed image;
- a glaucoma determination model generation unit for allowing multiple individual learning models of different types to be learned based on the multiple transformed images and generating a glaucoma determination model based on respective outputs of the learned multiple individual learning models;
- a processing unit for diagnosing a class of glaucoma for the original fundus image based on the glaucoma determination model;
- and
- a storage unit for storing the multiple individual learning models and the glaucoma determination model,
- wherein the data amplification unit designates multiple capture areas for generating the multiple transformed images within a range preset based on an optic disc detected from the preprocessed image, and
- wherein each of the multiple capture areas has a shape of a square, having sides of a preset length, in consideration of a size of the optic disc and has a center of gravity thereof located on a circumference of a virtual circle having a center of the optic disc as a center of the virtual circle, wherein a radius of the virtual circle is greater than that of a circle corresponding to a boundary of the optic disc.
