I have a matrix with 3 channels (HSV color space). Now for each matrix element I need to calculate my own norm defined by metric tensor, outcome should be single channel matrix:

I'm trying to find something like that it in documentation (I'm pretty sure I've seen it earlier), but so far without luck.

I need it to replace usage of cv::inRange.

I need it to replace usage of cv::inRange.. Instead two state result I need something more smooth (no thresholds).
