How MATLAB convert RGB to LAB?

Hi!

Can somebody answered me this worry

I know that MAtlab have rgb2lab command but i need know which method is used to do this convert.

I read that can use Lineal, Gamma, Cuadratic or Direct Model.

Matlab use someone of these or another?

Thanks a lot!

If you want more control than the documentation will provide, maybe you should consider implementing a conversion yourself, or look in the FEX if someone did (and mentions what conversion method they use).

Well, none of them will be accurate. But whether they will suffice depends on what you want to do. What do you want to do? By the way, I don't see any of those options as allowable options to rgb2lab().
