Abstract: When discriminating a plurality of types of objects, a plurality of local feature quantities are extracted from local regions in an image, and positions of the local regions, and attributes according to image characteristics of the local feature quantities are stored in correspondence with each other. Then, object likelihoods with respect to a plurality of objects are determined from attributes of feature quantities in a region-of-interest, an object whose object likelihood is not less than a threshold value is determined as an object candidate, and whether an object candidate is a predetermined object is determined.
