Calculating Valid Chroma?Please note, this blog has been archived and now lives at www.discretecosine.com
Does anyone have a good method for determining whether chrominance is legal, based on YUV values? I can go with RGB if need be as well. Best I've found is that the three RGB channels shouldn't average to greater than 75% of 255 in 8bit sampling, but I'm not really convinced that's accurate. Aren't the values in some way weighted based on the hue?
