No CUDA support in OpenCV 4.1.1?

[miguel.oyarzun]

It looks like CUDA support is NOT compiled into the OpenCV 4.1.1 build in Jetpack 4.4 DP [L4T 32.4.2]. Is that intentional?

You may have a part of the answer in this topic:

Is there a plan on next Jetpack release for opencv (cuda) support?

I think it’s mainly a QA topic. Opencv’s test suite can have hundreds of tests per module. Although many improvements are made from hundreds to a few tests failing, as far as I’ve been able to check a few weeks ago with a pre-4.3 version, not all are yet perfect and if one among the many tests failed, it would report the module as failing, even if this is just a corner case. I don’t know about NVIDIA’s QA requirements, it may be less or more restrictive… Someone else may better comment.
