CUDA acceleration on opencv is too slow

asked 2020-07-13 07:39:24 -0500

I use CUDA acceleration on opencv4.3, after using it, I spend 4S processing each frame of image, and then the following prompt appears!

cv::dnn::dnn4_v20200310::Net::Impl::initCUDABackend CUDA backend will fallback to the CPU implementation for the layer "_input" of type __NetInputLayer__
