再做图像处理时为什么要YUV与RGB的相互转换?
(1)RGB TO YCbCrY = 0.2990R + 0.5870G + 0.1140B;R-Y = 0.7010R - 0.5870G - 0.1140B;B-Y = -0.2990R - 0.5870G + 0.8860B;(2)RGB TO YUVY = 0.2990R + 0.5870G + 0.1140B;V = 0.5R - 4187G - 0.0831B;U = -0.1684R - 0.3316G + 0.5B;(3)YUV TO RGBR = Y + 1.14022V;G = Y - 0.34414U - 0.71420V;B = Y + 1.7720U;
