Abstract: An image recognition apparatus includes a processor including a plurality of arithmetic units; and a memory storing a plurality of data elements, each corresponding to one of candidate regions detected in an image and indicating a location and an evaluation value of the corresponding candidate region. The processor sorts the data elements by calculating in parallel, in reference to evaluation values, indexes each indicating a position of a corresponding one of the data elements in a sorted ordering and transferring in parallel, after the calculation of the indexes, the data elements based on the indexes. The processor selects part of the candidate regions based on the sorted ordering of the data elements.

Abstract: A control method includes: executing a first process that includes obtaining movement information on movement of an object from an image sequence; executing a second process that includes presuming a set of a candidate region in which an object may be present in a first image in the image sequence and an index indicating probability of presence of the object in the candidate region according to a feature amount of the first image; and executing a third process that includes determining a position of the object in the first image by using the set of the candidate region and the index presumed, wherein the second process includes correcting information obtained during the presuming based on the obtained movement information.

Abstract: A control method includes: estimating, in a first image within an image series, a plurality of sets including candidate regions and indexes according to image feature quantities of the first image, the candidate regions being regions in which presence of an object is estimated within the first image, the indexes being values indicating possibilities of the presence of the object in the candidate regions; obtaining movement information about movement of the object from the image series; correcting the candidate regions and the indexes in the plurality of sets based on the movement information obtained by the second processing; and determining the position of the object in the first image based on the plurality of sets including the corrected candidate regions and the corrected indexes.
