Abstract:
1. An image processing apparatus configured to identify tissues in respective parts of a tissue image, comprising: a tissue image subdivider configured to subdivide the tissue image for identification into a plurality of detecting local regions; a detector configured to detect texture feature values of the detecting local regions; and a determining unit configured to compare a detected texture feature value of a detecting local region of the plurality of detecting local regions to a learned feature value for identification associated with a predetermined tissue and, on the basis of the comparison result, determine whether or not the detecting local region belongs to the predetermined tissue, wherein the detector includes: a first extractor configured to extract, from the tissue image for identification, detecting pixel blocks of predetermined size, each detecting pixel block being centered about a respective center detecting pixel in one of the detecting local regions into which the tissue image for identification was subdivided; a first encoder configured to generate detecting encoded code patterns such that, for each extracted detecting pixel block, pixel values of a plurality of non-centered detecting pixels belonging to that detecting pixel block are encoded into one of multiple possible code patterns based upon a comparison between each of the plurality of non-centered detecting pixels with the center detecting pixel; and a first generating unit configured to generate a detecting local region histogram for each specified detecting local region, the detecting local region histogram indicating respective occurrence frequencies of the detecting encoded code patterns and generated for use as the texture feature value of that detecting local region.
