2013-04-24 17:08:47 -0600 | asked a question | How to change the parameters of the Optical Flow Dual TV L1 implementation of OpenCV 2.4.4? Hi, I somehow can't access / change the members of the TVL1 optical flow implementation (C++) after creating a pointer to it with cv::Ptr<cv::denseopticalflow> _flow = createOptFlow_DualTVL1(). I tried _flow->paramHelp("tau") and also _flow->info()->paramHelp("tau"). It gives me a "Bad argument (No parameter ´tau´ is foun)" error. Acquiring the list of parameters with getParams gives me an empty vector. Is this a bug or am I forgetting something? Example code i tried for parameter printing (actually mostly just copy & paste from here): parameters has the size 0 for me. I'm currently working with Visual Studio 2012. |
