Abstract
The invention provides an image recognition method. First, it is judged whether a set of discrete cosine transform (DCT) coefficients corresponding to an image and/or a set of texture parameters corresponding to the DCT coefficients exist. If the judgment is no, the image is selectively performed a DCT or an inverse discrete cosine transform (IDCT) to generate the set of DCT coefficients based on a format of the image. Based on the set of DCT coefficients, the set of texture parameters is then generated. Afterward, the set of texture parameters is compared with a set of target texture parameters to generate a recognition result.
