  • Patent number: 6061477
    Abstract: A digital image warper system produces a warped output image from an input image. The warper system increases the sampling rate of a sampled image above the Nyquist rate or samples an analog image at a higher rate than the Nyquist rate and prefilters the upsampled image to counteract filtering which may occur during the warping operation. The upsampled image is warped using an interpolator for resampling to produce a warped upsampled image. The interpolator is, for example, a low quality interpolator such as a bilinear interpolator. The warped image is then down-sampled to the same resolution as the input image to produce the warped image. Down-sampling and warping can be combined into one step by modifying the geometric transformation function implemented when warping the upsampled image.
