Abstract
There is provided a similar image providing device including: a lesion region extracting unit that extracts a lesion region from a subject diagnostic image; a local image feature extracting unit that extracts local image features; a quantizing unit that quantizes the local image features; a lesion classifying unit that classifies a lesion; a storing unit storing correlation coefficients between local image features and topic variables expressing degrees of progression or degrees of seriousness of lesions; an expected value estimating unit that acquires expected values of probabilities of occurrence of topic variables; an image storing unit that stores diagnostic images and the expected values; and a providing unit that provides diagnostic images corresponding to expected values of topic probabilities of occurrence that best approximate the expected values of the topic probabilities of occurrence.
