Abstract
A method of minimizing color aliasing artifacts from a color digital image having color pixels is disclosed. The method includes providing luminance and chrominance signals from the color digital image; using the luminance and chrominance signals to compute neighborhoods of pixels which are to be processed and wherein such neighborhoods of pixels are substantially bounded by pixels defining edges; producing low frequency chrominance signals in response to the chrominance signals; using the low frequency chrominance signals and the computed neighborhood of pixels to produce noise-cleaned chrominance signals; upsampling the noise-cleaned chrominance signals to produce upsampled noise-cleaned chrominance signals; and using the luminance signals and the upsampled noise-cleaned chrominance signals to provide a color digital image having reduced color aliasing artifacts.
