  • PROCESSING APPARATUS, FINGERPRINT IMAGE EXTRACTION PROCESSING APPARATUS, SYSTEM, PROCESSING METHOD, AND COMPUTER READABLE MEDIUM
    Publication number: 20220139105
    Abstract: A technique for accurately extracting a fingerprint image for accurate authentication from 3D tomographic luminance data of a finger at a high speed. A processing apparatus (11) according to the present disclosure includes means for, after performing edge detection processing on a tomographic image (101, 102, . . . 10 k, . . . , 10n) at each depth, calculating the total number of edge pixels in the tomographic image from 3D (three-dimensional) tomographic luminance data, and acquiring depth dependence of the number of edges (111, 112), and means for extracting a tomographic image having a striped pattern from the depth dependence of the number of edges and the 3D tomographic luminance data.
