A method of reducing color aliasing artifacts from a color digital image having color pixels including providing luminance and chrominance signals from the color digital image; downsampling the luminance and chrominance signals; using such downsampled luminance and chrominance signals to separate the image into textured and nontextured regions having boundaries; cleaning the downsampled chrominance signals in the textured regions in response to the boundaries of the textured region and the downsampled chrominance signals; cleaning the downsampled chrominance signals in the nontextured regions in response to the downsampled chrominance signals; upsampling the downsampled noise-cleaned chrominance signals; and using the luminance and upsampled noise-cleaned chrominance signals to provide a color digital image having reduced color aliasing artifacts.
A method of reducing color aliasing artifacts from a color digital image having color pixels comprising the steps of:
