Abstract: The provided is an image processing technology to avoid inaccuracy of inferring a position of an object due to wrong model assumption.An image processing device according to an exemplary aspect of the present invention includes: a matching unit 106 that estimates similarity of input image to particle images including areas of particles at relative positions, true positions of the particles in the particle images being given; and a calculation unit 108 that calculates positions of particles in the input image based on the similarity and the true positions.

Abstract: Provided is an information processing system configured to: receive a plurality of images; select a standard image; search, in extracting partial images for complementing a too bright region/too dark region in the standard image from a reference images, using correction images obtained by subjecting each of the images to multivalued processing for each division of luminance components, for regions having matching shapes of respective regions included in the correction image of the standard image and the correction images of the other images; and complement image portions corresponding to the too bright region and/or too dark region in the correction image of the standard image using image portions, which are matching regions and correspond to appropriately bright regions, to thereby generate a synthetic image. Each image is dividable into at least three values: a too bright region, an appropriately bright region, and a too dark region, and has a relationship in which a boundary luminance between the too bright region and the appropriately bright region aligns with a boundary luminance between the appropriately bright region and the too dark region in a darker image having an adjacency relationship therewith.
