How to convert image from rgb space to luv space?

Is there any built in command for converting RGB image to LUV?

You can use the makecform() function in the Image Processing Toolbox. First convert rgb into xyz, then convert xyz into uvL. (They seem to reverse the letters compared to most people for some reason.)

Dr. Stephen Westland, one of the leading color scientists in the world has a color science toolbox here that has the transform in it: http://www.mathworks.com/matlabcentral/fileexchange/40640-computational-colour-science-using-matlab-2e

You can find a bunch of color transforms here: http://www.easyrgb.com/index.php?X=MATH

File exchange has a colorspace transformations function. Googling turned up a few functions like this one which may or may not have been someone's homework assignment.
