Note that there are many ways of converting colour to greyscale. Any weighted sum of the colour components can be a greyscale conversion.

Your Y component of the ycbcr triplet is already such a weighted sum. So you could just use that as a greyscale image.

Otherwise, you can always

rgb2gray(ycbcr2rgb(yourimage))

edit: an r was missing. Thanks Image Analyst

Correction: rgb2gray(ycbcr2rgb(yourimage))
