  • Publication number: 20110142345
    Abstract: Provided are an apparatus and method for recognizing an image. In the apparatus and method for recognizing an image, various features can be extracted by a Haar-like filter using 1st to nth order gradients of the x- and y-axis of an input image, and the input image is correctly classified as a true or false image using, in stages, the extracted features of the input image, multiple threshold values for a true image and multiple threshold values for a false image. Accordingly, the apparatus and method achieve a high recognition rate by performing a small amount of computation. Consequently, it is possible to rapidly and correctly recognize an image, enabling real-time image recognition.
