Hi,

I want to use updateMotionHistory function. I can find doc or for opencv-3.0 . I have just download opencv and compile with success (General configuration for OpenCV 3.0.0-dev) and I cannot find include file for function definition. Where is include file for this function? Thanks for your help.

what about #include <opencv2/optflow/motempl.hpp> ? and then I guess you can call the function as cv::motempl::updateMotionHistory()

Thanks I can insert updateMotionHistory now. I use msvc 2012 so I have added in modules\line_descriptor\src\binary_descriptor.cpp:

int round(double d)
{
    return static_cast<int>(d + 0.5);
}

and in file modules\saliency\src\motionSaliencyBinWangApr2014.cpp and modules\optflow\samples\optical_flow_evaluation.cpp

#ifdef WIN32
    #ifndef NAN
        static const unsigned long __nan[2] = {0xffffffff, 0x7fffffff};
        #define NAN (*(const float *) __nan)
    #endif
#endif

and in file modules\line_descriptor\src\bitops.hpp change 0xFFFFFFFFFFFFFFFFLLU in 0xFFFFFFFFFFFFFFFFULL

^^ yea, known troubles with those ;)

there's a cvRound() function for the 1st problem.

It seems that opencv_adas project is an empty project

^^ yes. and some ms compilers fail to build, because there's nothing to export

cmake -DBUILD_opencv_adas=OFF
