Hi every body;
To convert an image an RGB image to L*u*V* color space i convert image to xyz then to l*u*v*....using that code:
>> cform = makecform('srgb2xyz');
>> xyz_img = applycform(img,cform);
>> cform = makecform('xyz2uvl');
>> luv_img = applycform(img,cform);
I wana to ask if their is any directly change from rgb to l*u*v*?
Thank You..

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().
