Abstract:
1. An object recognizing apparatus recognizing a target object image from images, comprising: pixel value distribution extracting means for extracting corresponding pixel value distributions of various regions in said object image and a background image existing as a background of said object image; and recognizing means for recognizing said object image based on difference in pixel value distributions of various regions extracted by said pixel value distribution extracting means, wherein said pixel value distribution extracting means divides said background image and said object image into a number of blocks, respectively, calculates distance between pixel value distributions of different blocks to find a distance map as a set of distance values between blocks, represents an element extracted from each distance map as a distribution of distance vector of a prescribed dimension, and calculates a discrimination axis for discriminating distribution of the distance value vector of the background image and the target image, respectively.
