1. A method for re-sampling an image having chromatic information and luminance information comprising the steps of:
- (a) re-sampling said luminance information using a first re-sampling process and attenuating at least a portion of lower frequency chromatic information with respect to at least a portion of higher frequency chromatic information resulting from said re-sampling of said luminance information;
(b) re-sampling said chromatic information of said image using a second re-sampling process, at least one of;
(i) re-sampling of said luminance information is different than said re-sampling of said chromatic information; and
(ii) said second process processes pixels of said image in a manner different than said first process;
(c) combining said re-sampled luminance information, said re-sampled chromatic information, and at least a portion of said higher frequency chromatic information into a re-sampled image.

31. A method for re-sampling an image comprising the steps of:
-
(a) re-sampling said image;
(b) filtering said image in a manner such that the luminous information has a non-uniform sampling rate;
(c) modifying said image by taking into account said non-uniform sampling rate in such a manner that reduces the chromatic artifacts of said image to less than it would have been had said non-uniform sampling been taken into account. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
