title: Get known position in one image to another using 8-point algorithm
body: <p>I have two images and and know the position of a point in the first image. Now I want to get the corresponding position in the second image.</p>
  <p>This is my idea:</p>
  <ul>
  <li>I can use algorithms such as <code>SIFT</code> to match keypoints (as seen in the image)</li>
  <li>I know the camera matrix using calibration with e.g. chessboards</li>
  <li>Using the 8 point algorithm I calculate the fundamental matrix <code>F</code></li>
  </ul>
  <p>Can I now use <code>F</code> to calculate the corresponding point?
