Hi guys,

I’m trying to use OpenCV 3.2 on Nvidia TX1 to run a simple pedestrian detection program. I noticed in OpenCV 3.2, the gpu::HOGDescriptor is no longer avaliable. Does any one know what is the relative gpu version of HOGDescriptor for OpenCV 3.2?
What I have is something like this,

GpuImg.upload(current_frame);
  	    cuda::resize(GpuImg, rGpuImg, Size(GpuImg.cols * scale, GpuImg.rows * scale));
        hog.detectMultiScale(rGpuImg,found,0,Size(8,18), Size(32, 32), 1.05, 2);
		Mat rInimg;
 		rGpuImg.download(rInimg);

Thank you!

Hi,

Thanks for your question.

Cascade-Haar is available.

classifier = cv::cuda::CascadeClassifier::create(...);
