| 2013-07-09 11:19:44 -0600 | commented answer | USB video capture to cuda Thanks you so much for your response, I started with an apology as I have been trying to get some help on the Nvidia CUDA dev forum for months and no one responded, should have come to the open community first. I reversed the course I was taking, I had installed MS VS and the Nvidia dev kit, created a CUDA project as a base and tried to get OpenCV integrated that way. So I binned that and have followed the tutorial you linked, and now have a working real time edge detection from my cam :) As long as I can offload all the video and frame processing to the GPU I guess I don't need actual CUDA code? I intend to process something like 10 frames a second of 1080i video, detecting edges/boxes and from there comparing with templates to make decisions as to what is on ... |
| 2013-07-03 16:50:19 -0600 | asked a question | USB video capture to cuda First off sorry I'm new to Windows and CUDA programming, well all of CV really. I have a Diamond GC1000 USB video capture device, I want to be able to feed the HD video stream from the device into my GPU so that I can real time process the frames, but I have no idea where to start. My basic stumbling block is I don't understand how I interface my CUDA code to the USB drivers, I have my CUDA code that I can say perform edge detection on a static PNG, what I need to do is replace that PNG with the stream frames from the GC1000. Any guidance would be appreciated! Thanks Joby |
