ABSTRACT:
A system and method that scale a first image to a second image. The scaling factor between the first image and the second image may be used to determine the number of pixels from the first image to be used to produce a pixel of the second image. The number of pixels from the first image may be utilized to pre-compute coefficients of a filter to be applied to the pixels from the first image. The location of the pixels from the first image relative to the pixels of the second image may be utilized to compute the filter coefficients. The coefficients may be computed using a Sinc function. The predetermined coefficients may be organized according to the order in which the pixels from the first image are to be processed to produce the second image.
