C++ (Cpp) OutputArray::depth Examples

Example #1

File: vizcore.cpp Project: ArkaJU/opencv

void cv::viz::readTrajectory(OutputArray _traj, const String& files_format, int start, int end, const String& tag)
{
    CV_Assert(_traj.kind() == _InputArray::STD_VECTOR || _traj.kind() == _InputArray::MAT);

    start = max(0, std::min(start, end));
    end = std::max(start, end);

    std::vector<Affine3d> traj;

    for(int i = start; i < end; ++i)
