Pattern recognition apparatus and method for recognizing a recognition object by comparing with pre-registered models. From an inputted image, multiple feature points is extracted; therefrom, combination of multiple feature points is selected; and from the multiple selected feature points, bases which represent the positions and positional relations of these feature points are calculated. A partial pattern of said recognition object corresponding to each of said calculated bases is extracted from said image; and a search place on said table is decided based on an invariant parameter to geometric transformation of the partial pattern. The similarity between the partial pattern of said model registered in said search place on the table and the partial pattern of said recognition object is judged; and a plurality of hypothesis information showing that said recognition object exists in the image is generated based on the similarity between both partial patterns. The identification, position etc are decided based on said information.
