C++ (Cpp) homMat Examples

Example #1

File: mitkTransform.cpp Project: zomboir/MITK

  vnl_matrix_fixed<mitk::ScalarType, 4, 4> Transform::GetMatrix()
      const
  {
    vnl_vector_fixed<mitk::ScalarType, 3> transl = this->GetVnlTranslation();
    vnl_matrix_fixed<mitk::ScalarType, 3, 3> rot = this->GetVnlRotationMatrix();

    vnl_matrix_fixed<mitk::ScalarType, 4, 4> homMat;
    homMat.set_identity();
    //std::cout << homMat << std::endl;
    for(unsigned int i=0; i<rot.rows(); ++i)
      for(unsigned int j=0; j<rot.cols(); ++j)
        homMat(i,j) = rot(i,j);
    for(unsigned int i=0; i<transl.size(); ++i)
      homMat(i,3) = transl[i];

    return homMat;
  }

Example #2

File: Morphing.cpp Project: HVisionSensing/ImageMorphing

{
	int num_pts = pts.size();
	cv::Mat homMat(3, num_pts, CV_32FC1);
	for(int i=0; i<num_pts; i++){
		homMat.at<float>(0,i) = pts[i].x;
		homMat.at<float>(1,i) = pts[i].y;
		homMat.at<float>(2,i) = 1.0;
	}
