2017-07-17 05:41:42 -0600 | asked a question | GPUMat and Mat Hi, I need to do some operation on matrix (subtract, reshape, roi, ...) and I use cuda for parallel treatments. But in the kernel I thought GPUMat was Mat but for kernel. It wasn't the cas and I ask what is the meaning of GPUMat and how do the operation in my kernel without Mat. Thanks |
2017-07-11 16:07:40 -0600 | asked a question | CUDA more slower than CPU Hi, I have made my own package of opencv 3.2 with CUDA 8.0 and I run it with Microsoft Visual studio 2015 but when I tried with https://devblogs.nvidia.com/parallelf... my time with GPU are more slower than CPU. I built it in x64 and debug mode, I have an error with <<< for the kernel but the program compil and run Do you have any idea ? Thanks |

2017-06-27 13:57:25 -0600 | asked a question | Problem with compiling and ts.hpp Hi, I work on stereo vision and I need the extra module stereo so I deciced to make my own opencv bundle with this module. But when I make install my output file doesn't contain the ts file and I need it to test the sample. During the Cmake step, I check and the build opencv_ts is check.
