Abstract
By performing, on an original image having pixel values representing depths of positions on a textured surface of a target object, a conversion for making an element histogram of a steerable pyramid of the original image the same as or similar to an element histogram of a steerable pyramid of a reference image having pixel values representing depths of positions on a textured surface of a reference object, for each spatial frequency band and each orientation band, histogram modulated images are obtained, and the histogram modulated images obtained for the spatial frequency bands and orientation bands are synthesized to obtain an image corresponding to a modulated image having pixel values representing depths of positions on a textured surface of a modulated object.
