摘要： When groups of coordinates of face areas respectively contained in mutually different frames are within a predetermined error range, a face attribute assigning unit assigns mutually the same face attribute value to each of the face areas. In the case where a difference in the feature amounts between the frames is within a predetermined error range, a similar shot detecting unit detects that the shots from which the frames have respectively been extracted are similar shots to each of which mutually the same shot attribute value is assigned. In the case where it is judged that face areas that respectively appear in the frames contained in the similar shots and to which mutually different face attribute values have respectively been assigned represent the face of mutually the same person, the face attribute re-assigning unit assigns mutually the same face attribute value to each of the face areas.

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

摘要： An image input unit inputs an image including a user's face area to specify the user's gaze or face direction. A pattern generation unit generates an input pattern that can be compared with each dictionary pattern from the image. A dictionary unit previously stores a plurality of dictionary patterns each of which differently corresponds to the user's gaze or face direction. A pattern comparison unit respectively calculates a similarity degree between the input pattern and each of the dictionary patterns by comparing the input pattern with each of the dictionary patterns. A gaze detection unit detects the user's gaze or face direction based on the similarity degree.
