Hi,
I need to free memory allocated by UMat during code execution, so I don't have an out of memory error. I'm using OpenCV 3.1.0 with CUDA 7.5. Here's what I've tried:
cv::cuda::DeviceInfo di;
size_t totalMemory;
size_t freeMemory;
di.queryMemory(totalMemory, freeMemory);
cout << freeMemory/1024/1024 << endl;
UMat m = UMat::zeros(1000,1000, CV_8SC1);
di.queryMemory(totalMemory, freeMemory);
cout << freeMemory/1024/1024 << endl;
m.release();
di.queryMemory(totalMemory, freeMemory);
cout << freeMemory/1024/1024 << endl;
return 0;
Output:
1527
1497
1498
