System information (version)

Detailed description

I tried to call

cv::cuda::FastFeatureDetector::create with the argument type with other value than TYPE_9_16 and the program crashed due to an assertion. Can someone explain this.

The reason I was doing this is this solution to the problem that CUDA Fast detector does not detect all keypoints as stated here

Steps to reproduce

```.cpp
cv::Ptr<cv::cuda::FastFeatureDetector> CUDA_detector = cv::cuda::FastFeatureDetector::create(32,true,1,5000);
```
