Installing opencv 3.1 on tk1

I was wondering if anyone has done this and if the new functions are worth the loss in performance? I currently have 2.4.10 installed with the latest version of jetpack. However, I want to be able to use auto white balance and color correction which are found only in 3.1

I recall reading somewhere here that some functions are slower, and others are faster (probably things that aren’t GPU-accelerated). There are installation instructions here.
