| 2013-02-26 22:24:16 -0600 | asked a question | Segmentation fault when using "gpu::PyrLKOpticalFlow::dense" I am using OpenCV-2.4.3 on Ubuntu 11.10. When I run the demo algorithm "pyrlk_optical_flow_gpu" provided in the sample, I get a segmentation error!! It seems that this error is in the function "PyrLKOpticalFlow::dense" Did any one experienced the same problem?? Is it a bug in that release of OpenCV or am I doing something wrong? Any help or feedback will be very appreciated. Thanks |

VGA or HD)? Which optic flow algorithms are ported into GPU and which ones are more efficient OR/AND accurate? Thank you very much. |
