  • Method and system for resizing an image
    Patent number: 8873884
    Abstract: There is disclosed a method and system for resizing a digital image wherein a RGB image is converted into an YCbCr image (Y, Cb, Cr planes). Thereafter, a discrete cosine transform (DCT), followed by a specific inverse cosine transform (IDCT) is performed on each row/column of the Y, Cb, Cr planes. The mentioned specific operation corresponds to a type of homothetic matrix, which dimensions are defined by a scaling factor. In order to produce a scaled image, the scaled Y, Cb, Cr images are transformed to an RGB image for display.
