why does setting target as Opencl slow down DNN?
I have used OpenCV DNN module for object detection. It is seen that while setting preferable target of network to Opencl the forward pass slows down by a factor of ~10x( Windows as well as embedded platforms). I can even detect GPU device with OpenCL support (OpenCL C 1.2 ). Is there any reason why this could be happening?
could you add the output of:
to your question ? (this will show the GPU features)
hi i have the same problem . i don't the meaning "opencv_version -opencl" . this is a instruction code in makefile????could you explain it more clearly??
