MATLAB: Converting gray scale to ycbcr?

conversionconvertgrayImage Processing Toolboxrgbsrgbycbcr

Is there any way by which we can convert a gray scale to Ycbcbr???

Best Answer

A greyscale image has no colour information, but you can still represent it as ycbcr if you wish - though it's not clear why you'd want to, since the chrominance planes will be constants. Anyway, this will convert, assuming you're starting from a 2D greyscale image:
    rgbimage(:,:,1) = greyimage;
    rgbimage(:,:,2) = greyimage;
    rgbimage(:,:,3) = greyimage;
    ycbcrimage = rgb2ycbcr(rgbimage);
You can also convert a colormap using the same function, if that's what you want to do.
