摘要： Method and apparatus for providing a standardized measure of accuracy of each biometric device in a biometric identity authentication system having multiple users. A statistical database includes continually updated values of false acceptance rate and false rejection rate for each combination of user, biometric device and biometric device comparison score. False acceptance rate data are accumulated each time a user successfully accesses the system, by comparing the user's currently obtained biometric data with stored templates of all other users of the same device. Each user is treated as an “impostor” with respect to the other users, and the probability of an impostor's obtaining each possible comparison score is computed with accumulated data each time a successful access is made to the system. The statistical database also contains a false rejection rate, accumulated during a test phase, for each combination of user, biometric device and biometric device comparison score.

摘要： A method and an apparatus are presented for correcting corner images of an integrated circuit pattern, for example, in an real image produced by optical scanning and deleting defects from the corner sections. Design data describing rectangular or trapezoidal patterns are expanded in a design data expansion section in multi-level gradations to produce a reference data for each pixel having resolution capability less than the inspection resolution capability. In a reference image forming section, based on the edge position of the real image, the reference data are processed to produce a reference image by rounding off the corner section and the line width while maintaining multi-level gradations. The boundary regions are blended using optical point spread functions obtained from the real image.

摘要： An image processing apparatus and method and a provision medium arranged to perform image learning and image recognition in a short time. An image difference detector computes a differential image between an image stored in a frame buffer and an image stored in another frame buffer, and also computes the centroid of the differential image. A information collector forms RGB histogram data and binary data of a peripheral area about the centroid obtained by the image difference detector. A category former formed by a Kohonen network forms a category based on the RGB histogram data and binary data. A category statistic processor performs statistical processing of the categories output from the category former, and outputs a processing result to a learner formed by a recurrent neural network.

摘要： The present invention provides an image collation device having a simple whole structure which is applied, for example, as a fingerprint collation device. Linear images cut from the one image is stored in a memory means, and the other image is collated with the stored liner images. Thereby the image data of the linear images can be recorded in a memory means having a small capacity.
