Abstract
A method for representing a subportion of a color image as an output pixel, the subportion of the color image being contained within a portion of the color image comprising a plurality of locations arranged as a grid defining a corresponding array of color component values, the method comprising the steps of: providing a first plurality of first coefficients corresponding in number to a first plurality of positions along a first dimension of the array; providing a second plurality of second coefficients corresponding in number to a second plurality of positions along a second dimension of the array; providing a third plurality of third coefficients corresponding in number to a third plurality of positions along a third dimension of the array; for each ordered pair of positions along the second and third dimensions of the array, providing a weighted color component value sum comprising a weighted sum of the color component values along the first dimension at said ordered pair of positions, each color component value along the first dimension at said ordered pair of positions being weighted by the first coefficient corresponding to the position of said color component value along the first dimension; for each position along the third dimension of the array, computing a weighted sum of the weighted color component value sums along the second dimension at said position along the third dimension, each weighted color component value sum along the second dimension at said position along the third dimension being weighted by the second coefficeint corresponding to the position of said weighted color component value sum along the second dimension; and computing a weighted sum of the weighted sums of the weighted color component value sums along the third dimension, each weighted sum of the weighted color component value sums along the third dimension being weighted by the third coefficient corresponding to the position of said weighted sum of weighted color component value sums along the third dimension.
