Abstract
Images and video sequences often have to be scaled to a different size. We present binary interpolation filters obtained from the Mth band eigenfilters via the lifting steps for the sampling rate alteration. The binary filters are implemented with only the shift and add operations, providing an efficient way to perform image size conversion. Scaled images using the proposed filters show superb image quality
