Abstract
A similarity determination apparatus comprising a processor configured to: classify each pixel of a first medical image into at least one of a plurality of types of findings; calculate a first feature amount for each classified finding; set a weighting coefficient indicating a degree of weighting which varies depending on a size of each finding for each classified finding; derive an adjusted weighting coefficient by adjusting the weighting coefficient for each of a plurality of finding groups, into which the plurality of types of findings are classified; and derive the similarity between the first medical image and a second medical image by performing a weighting operation for the first feature amount for each finding in the first medical image and a second feature amount for each finding calculated in advance in the second medical image, for each of the finding groups on the basis of the adjusted weighting coefficient.
