Hi, I just use cv::resize() function to resize an image. And it turns out that it will occupy GPU graphic memory.
cv::resize(mat, mat, cv::Size(1920,1080)) occupies 147MB.
System Info:
Opencv 3.3.1 without CUDA support. (cv::cuda::setDevice() gives "opencv is compiled without CUDA")
CUDA 10.0
How does this happen and how to solve the problem, besides version update/backup?
