Abstract
A novel search method having an advantage over the DSR 472 method the search accuracy of which is currently said to be the highest level is proposed. At the feature value computation stage, the two-dimensional image used in computation of the three-dimensional model feature value (excluding a contour feature value) is corrected so that the gray scales of the pixels are emphasized more as the distance from the center of the two-dimensional image increases.
