Webb7 juli 2012 · YCBCR = rgb2ycbcr (RGB) converts the truecolor image RGB to the equivalent image in the YCbCr color space. RGB must be a M-by-N-by-3 array. If the input is uint8, YCBCR is uint8, where Y is in the range [16 235], and Cb and Cr are in the range [16 240].

Which conversion formula does matlab use for rgb2ycbcr?

WebbPython2.net WebbFor example, use (255, 255, 255) as RGB input. You'll get Y=240 (clipped), Cr=128, Cb= 128. But if you try to convert back, due to clipping which gave you 240 instead of 255, you'll get (240, 240, 240) as RGB pixel. This is the root of my problem - I get gray with reduced brightness.
