  • Altering spatial characteristics of a digital image
    Patent number: 4653013
    Abstract: The values of pixels in a new image matrix are obtained by mapping pixels of the new matrix in the old matrix and then using polynomial interpolation of a plurality of values of pixels in the old matrix to obtain values of interim pixels in the new matrix and then using polynomial interpolation of a plurality of interim values to obtain final values of pixels in the new matrix. A precalculated table of weighting coefficients based on offset of a new pixel from an adjacent old pixel is used to expedite the polynomial interpolation.
