I have been using haarcascades_cuda/haarcascade_frontalface* with cv::cuda::CascadeClassifier (for a while now) using OpenCV 3.4.1 and it works very well!
However, I would really like to train using my own data. I have seen a lot of threads suggesting that this isn't really supported for the cuda class anymore. Is that so? Or is there a way to do it?
Also, is the training data for the existing haarcascade_frontalface* classifiers available?
Thank you!
