Hi,

Actually, I am not sure if there is any direct converter to convert an RGB image to a UVL color model, but you can simplify this as below:

I = rgb2xyz(I);
cform = makecform('xyz2uvl');
I = applycform(I,cform);

It's not in the list of available transforms so no, there is no way to go from RGB to LUV directly in one call to makecform().
