Reducing color aliasing artifacts from color digital images |
摘要 |
<p>A method of reducing color aliasing artifacts from a color digital image having color pixels includes providing luminance and chrominance signals from the color digital image; using such luminance and chrominance signals to separate the image into textured and nontextured regions having boundaries; downsampling the chrominance signals and texture region mapping; producing cleaned chrominance signals in the textured regions in response to the boundaries of the textured region and chrominance signals; producing cleaned chrominance signals in the nontextured regions in response to the chrominance signals; upsampling the 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.
