    摘要: A user authentication method and apparatus using a face image are provided. The method includes transforming a face image in a normalized spatial domain into frequency-domain data, extracting valid transform coefficients from the frequency-domain data based on energy-concentrated region information, extracting a feature vector from the extracted valid transform coefficients, and performing user authentication by comparing the extracted feature vector with a previously registered feature vector. Accordingly, it is possible to perform user authentication using a face image while using a minimum data dimension, thereby improving the speed and precision thereof.

    摘要: Disclosed herein is an object image capture apparatus. The object image capture apparatus includes a first camera unit, a second camera unit, and a control unit. The first camera unit obtains a wide-area view image by capturing a wide-area view region. The second camera unit obtains a close-up view image by capturing the close-up view region of the wide-area view region. The control unit controls the second camera unit by dividing the wide-area view image into a plurality of blocks, analyzing the resulting blocks, and defining a target block, in which a moving object is detected, as a close-up view region from among the plurality of blocks.

    摘要: Provided are a method and apparatus for reducing picture, which can obtain a reduced picture by previously creating a picture reduction map that stores effective-pixel locations selected according to a picture reduction scale and a picture reduction algorithm, and then matching an input picture with the picture reduction map. The method for reducing picture includes constructing a picture reduction map according to a size of an incoming picture, and generating a sub-picture for reduction of an input picture by using the picture reduction map.
