OCULAR FUNDUS IMAGE PROCESSING METHOD, OCULAR FUNDUS IMAGE PROCESSING DEVICE, OCULAR FUNDUS IMAGE PROCESSING PROGRAM, AND RECORDING MEDIUM HAVING SAID PROGRAM RECORDED THEREON

摘要

An ocular fundus image processing device 1 is provided with: an image input unit 3 which acquires a first ocular fundus image generated by shining exciting light of a blue wavelength onto the ocular fundus of a subject, and a second ocular fundus image generated by shining exciting light of a green wavelength onto the ocular fundus of the subject; a model generating unit 7 which employs training to generate three trained models for predicting a correction factor for calculating an amount of macular pigment of the subject from input images including the first ocular fundus image and the second ocular fundus image, using three different initial values; a factor predicting unit 9 which predicts three correction factors by inputting the input images including the first ocular fundus image and the second ocular fundus image into the three trained models; a factor deriving unit 11 which calculates a statistical value with respect to the three correction factors, and derives the statistical value as the correction factor for the subject; and a pigment amount calculating unit 13 which calculates the amount of macular pigment of the subject on the basis of the first ocular fundus image and the correction factor for the subject.
