ABSTRACT:
A method for resizing images using the inverse discrete cosine transform (IDCT). The method enables digital video processing devices such as DVD players, digital broadcast receivers, or HD TVs to enlarge an original image to an arbitrary size without resulting in distortions in the enlarged image, thereby preventing deteriorated image quality.
