cvtColor는 sRGB 색상 공간에서 비선형성을 처리합니까?

I am wondering whether OpenCV has functions to handle the non-linearities in the sRGB color space.

Say I want to convert an JPEG image from sRGB color space into XYZ color space. As specified in this [Wiki page](https://en.wikipedia.org/wiki/SRGB#Specification_of_the_transformation), one needs to first undo the nonlinearities to convert to linear RGB space, and then multiply with the 3x3 color transform matrix. However, I couldn't find any such discussions in the [cvtColor](http://docs.opencv.org/modules/imgproc/doc/miscellaneous_transformations.html#cvtcolor) documentation. Did I miss something?

Thanks a lot in advance!
