Convert RGB Image to YCbCr color space

YCbCr=rgb2ycbcr(enhancedImg);

Lum=mean2(YCbCr);

Above code produces error like..........

Error using rgb2ycbcr

Expected input number 1, RGB, to be real.

Error in rgb2ycbcr>parse_inputs (line 134)

validateattributes(X,{'uint8','uint16','single','double'},{'real'}, ...

Error in rgb2ycbcr (line 49)

rgb = parse_inputs(varargin{:});

Error in file1 (line 93)

YCbCr=rgb2ycbcr(enhancedImg);

Apparently your input is complex, not real. How you should fix that depends on your specific situation.

rgb2ycbcr(I) works well for normal(raw) image. but it gives error for enhanced(Gamma correction) image....why??

is there any matlab comment for convert complex image to RGB image?

You could use the real or abs functions, but I don't know if that makes sense for you.
