C++ (Cpp) Mat_::elemSize Examples

Example #1

File: cvFuncs.cpp Project: bkap/Mobile_Robotics

void writeMat(cv::Mat_<T>& mat, char* file){
	ofstream* ofile = new ofstream(file,ofstream::out|ofstream::binary);
	(*ofile)<<mat.rows<<" ";
	(*ofile)<<mat.cols<<" ";
	(*ofile)<<mat.type()<<" ";
	(*ofile)<<mat.total()*mat.elemSize();
	
	ofile->write((char*) mat.data,mat.total()*mat.elemSize());
	ofile->close();
}

Example #2

File: opencv_serialization.hpp Project: Cerarus/v4r

    void serialize(Archive & ar, ::cv::Mat_<T>& m, const unsigned int version)
    {
      if(Archive::is_loading::value == true)
      {
        int cols, rows;
        size_t elem_size, elem_type;

        ar & cols;
        ar & rows;
        ar & elem_size;
        ar & elem_type;

        m.create(rows, cols);

        size_t data_size = m.cols * m.rows * elem_size;
        ar & boost::serialization::make_array(m.ptr(), data_size);
      }
      else
      {
        size_t elem_size = m.elemSize();
        size_t elem_type = m.type();

        ar & m.cols;
