Abstract
An image processing apparatus includes an object-feature-information storage unit configured to store feature information of a predetermined object; an image inputting unit configured to input an image; an object detecting unit configured to detect an object contained in the input image; an attribute determining unit configured to determine an attribute of the detected object; a feature-point determining unit configured to determine, according to the determined attribute, positions of feature points to be set in the input image; and a similarity calculating unit configured to calculate, by comparing feature information stored in the object-feature-information storage unit to feature information at feature points set in the input image, similarity between an object corresponding to the feature information stored in the object-feature-information storage unit and the detected object.
