I have try to train my classifier using opencv_traincascade in my machine. When run it, it utilize 100% of my CPU but not use my GPU. I have install OpenCV 3.x in my Ubuntu 16.04. And I have GeForece GTX 1080 Ti/PCIe/SSE2. I success install the driver with CUDA 8.0. How I can use the GPU instead of using CPU? I use below script to train the module in terminal
opnencv_traincascade -data data -vec positives.vec -bg bg.txt -numPos 37000 -numNeg 756 -numStage 20 -w 20 -h 20
Any configuration I need to set to use the GPU?
