Chroma subsampling
A chroma subsampling having reduced artifacts is achieved by detecting high contrast areas in a luminance channel of an image to be chroma subsampled so as to partition the image into a first region composed of the high contrast areas and a second region distinct from the first region, with chroma s...

| description | A chroma subsampling having reduced artifacts is achieved by detecting high contrast areas in a luminance channel of an image to be chroma subsampled so as to partition the image into a first region composed of the high contrast areas and a second region distinct from the first region, with chroma subsampling the image in the first region using a first chroma subsampler and chroma subsampling the image in the second region using a second chroma subsampler, with the first chroma subsampler having a higher edge preserving property than compared to the second chroma subsampler. Thereby, bleeding artifacts may be avoided at least partially, while the saturation of the image may be substantially preserved. |
