  • Patent number: 5917961
    Abstract: Methods and apparatus are provided for processing a source image in an image processing system including an electronic digital computer and image processing software for operating the computer. The source image is processed by convolution of pixels of the source image with coefficients of a convolution kernel to provide an output image. A lookup table is generated before new pixel values are determined. The table includes products of each coefficient and each possible value of the pixel in the source image. For each of the coefficients, the product that corresponds to the pixel value in a convolution window is accessed in the table. The accessed products are summed to provide a new pixel value in the output image. The steps of accessing the products in the table and summing the accessed products are repeated for each of the source pixels being convolved.

  • Patent number: 5847714
    Abstract: Methods and apparatus for generating pixel values in a magnified destination image of an object are provided. The pixel values in the destination image are generated from a source image of the object. A value of a first pixel in each row of the destination image is determined by transforming the first pixel to a first resampled point in the source image and by vertical interpolation between vertically-aligned neighbor pixels to provide intermediate pixel values followed by horizontal interpolation between the intermediate pixel values to provide the value of the first pixel. Each subsequent pixel value that has the same neighbor pixels as a previous resampled point is determined by transforming the subsequent pixel to a subsequent resampled point and by a single horizontal interpolation between the intermediate pixel values of the previous resampled point.
