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 .
