Abstract: In parallel with an operation of browsing a pathological-tissue image, retrieval of similar cases from past cases using image information about the pathological-tissue image is automatically performed. An analysis apparatus of the present disclosure includes a first setting unit configured to set sample regions in an analysis target region of an image obtained by imaging of a biologically-originated sample, on the basis of an algorithm; a processing unit configured to select at least one reference image from a plurality of reference images associated with a plurality of cases, on the basis of images of the sample regions; and an output unit configured to output the selected reference image.

Abstract: There is provided an information processing device including a storage unit that stores first annotation data generated from image data of a biological specimen and conversion processing information, a conversion unit that converts, using the conversion processing information, the first annotation data into a plurality of second annotation data incidental to the first annotation data, and an output unit that outputs the first annotation data or the second annotation data.

Abstract: Making it possible to improve accuracy of machine learning. A determination support device includes: a derivation unit (100) that derives an estimation result of determination on a first pathological image obtained by imaging a biological sample, the derivation being performed using a multi-stage trained model in which class classification can be set in each stage.

Abstract: An estimation result can be more effectively utilized. An information processing apparatus includes a deriving unit (100) that derives an estimation result of diagnosis for a second pathology image using a trained model on which learning has performed using training data including a plurality of first pathology images, and an identifying unit (100) that identifies a basis image that serves as a basis for derivation of the estimation result by the trained model from the plurality of first pathology images.

Abstract: The usability in annotating an image of a subject derived from a living body is improved. An image analysis method is implemented by one or more computers and includes: displaying a first image that is an image of a subject derived from a living body; acquiring information regarding a first region based on a first annotation added to the first image by a user (S101); specifying a similar region similar to the first region from a region different from the first region in the first image, or a second image obtained by image capture of a region including at least a part of a region of the subject subjected to capture of the first image, based on the information regarding the first region (S102, S103); and displaying a second annotation in a second region corresponding to the similar region in the first image (S104).
