摘要

A discriminator includes a common learning unit and a plurality of learning units that are connected to an output unit of the common learning unit. The discriminator is trained, using a plurality of data sets of a first image obtained by capturing an image of a subject that has developed a disease and an image data of a disease region in the first image, such that information indicating the disease region is output from a first learning unit in a case in which the first image is input to the common learning unit. In addition, the discriminator is trained, using a plurality of data sets of an image set obtained by registration between the first image and a second image whose type is different from the type of the first image, such that an estimated image of the second image is output from an output unit of a second learning unit.

說明書

According to the apparatus, method, and non-transitory computer readable recording medium storing program for training a discriminator discriminating a disease region, the discriminator discriminating a disease region, the disease region discrimination apparatus, and non-transitory computer readable recording medium storing disease region discrimination program of the present disclosure, it is possible to discriminate a disease region, using a limited amount of data, even in an image in which it is difficult to prepare a large amount of data indicating a correct disease region.
