Nice presentation, I hadn’t seen that one before.
I would say they didn’t every get around to removing that limitation. I can’t remember exactly what happened, but it definitely seemes like the cuda backend was deprioritized, maybe it had something to do with Intel taking the reigns maybe not.
Essentially some routines use constant and texture memory and some do not, and unfortunately the best way to check 100% is to look at the source code.
Simple routines such as resize, colour conversion, thresholding etc. are unlikely to have a problem but the routines you are interested in rectification, block matching etc. are more likely to.
