It seems you have two versions of OpenCV installed, and the linker tries to use a different one for linking than the one used to compile your code. The simplest way is to remove all the other OpenCV versions, and then a possible wrong library path will be more explicit (somelib.so missing) Or, check all the settings PATH, linker …

Web8 de jun. de 2012 · 1 answer. This is the proxy class for passing read-only input arrays into OpenCV functions. Inside a function you should use _InputArray::getMat () method to construct a matrix header for the array (without copying data). _InputArray::kind () can be used to distinguish Mat from vector<> etc., but normally it is not needed.cv::EM requires and InputArray with only 1 channel if I define SampleType as cv::Vec or cv::Matx and SampleContainerType as cv::Mat_ and populate it, all is correct, m_Samples have correct structure and 1 channel. When the samples arrive as InputArray to EM em.cpp#L83 it turns magically to 2 channels matrix.
