Abstract: When first and second images are input, a partial image feature calculating unit calculates feature values of partial images of the two images. A maximum matching score position searching unit searches for a position of the second image that attains to the highest matching score with each of the partial images of the first image. A movement-vector-based similarity score calculating unit calculates similarity between the first and second images, using information related to that partial image whose movement vector has direction and length within a prescribed range, which movement vector representing positional relation between a reference position for measuring, for each of the partial images, the position of the partial image in the first image and the position of the maximum matching score corresponding to the partial image searched out by the maximum matching score position searching unit. The images as the object of collation may belong to the same category classified based on the feature values.

Abstract: An image matching device capable of matching two images performs the following processes in order to shorten a processing time and reduce power consumption. Template matching is performed between a first image and a second image using a predetermined partial image of the first image, and the similarity between the two images is calculated. The similarity thus obtained is compared with a predetermined threshold. Only upon determination that the similarity obtained and the predetermined threshold neither coincide not fail to coincide with each other, the partial image used for template matching is gradually increased until the similarity and the predetermined threshold come to coincide or fail to coincide with each other. Then, template matching is performed again and the similarity between them is calculated.

Abstract: A data-driven type information processor includes a ifinction processor manipulating contents in a data packet, a program storage unit storing a data flow program used by the function processor, and a branch unit controlling data flow whether to allow flow of a data packet within the processor or to provide the data packet to the outside thereof When a program is debugged, the portion of the program where a data packet is to be dumped (and checked) is directly designated by writing an instruction in a program that is stored in advance in the program storage unit. When the instruction code is encountered, the packet is dumped to the outside so that debugging of the program can be carried out by confirming the contents in the data packet that is output.

Abstract: An image comparing apparatus receives two images to be compared with each other. For each of the two images, respective feature values of partial images in the image are determined. With respect to each partial image in one of the images, the position of a partial image that is in the other image and that has the maximum score of matching with the partial image in that one image is searched for. The search range is limited to partial images selected according to three or five different feature values determined in advance. Then, the similarity score representing the degree of similarity between these two images is calculated, based on information about a movement vector indicating a relation between a reference position for locating the partial image in one image and the maximum matching score position that is searched for with respect to the partial image. Images to be searched belong to the same category as that of the partial image.

Abstract: Rectangular partial areas “Ri” for use in template matching in a process of determining match/mismatch between fingerprint images are spread adjacently to each other in one of the images. A boundary-including partial area is set in a portion including a crossing point of cross-shaped boundaries defined by the four neighboring partial areas. The plurality of partial areas formed of the neighboring partial areas and the boundary-including partial area are used as a template so that the number of the partial areas can be increased while ensuring a certain size of the partial area. Further, the boundary-including partial area covers the boundary between the neighboring partial areas so that continuity of image data at the boundary between the neighboring partial areas can be reflected in the determination of the match/mismatch between the images.

Abstract: In collation determination of an input biometric data and a plurality of reference data stored in advance, when a biometric data collating apparatus according to the invention determines that the reference data matching with the biometric data is present, the biometric data collating apparatus updates a current reference order ordidx of the reference data determined as matching data to Order[0] representing a leading place in a collation order table.

Abstract: In a biometric data collating apparatus according to the invention, when a reference data matching with a biometric data is present, each of collation order determination values is multiplied by a FREQFIX value. One is further added to the collation order determination value corresponding to the reference data matching with the biometric data. A comparison is made between the updated data, and the reference data are sorted in a descending order of the collation order determination value.
