Here is a sequence of images of a ballad in the forest. This scene
is observed by a tracking drone...

     <https://www.youtube.com/watch?v=46VWJ6-YqtY>

The camera's movement is estimated in the images using a projective
dominant motion measurement. The presence of a man in the image sequence
does not interfere with trajectory estimation, because the character
occupies a position in the field of vision that is not dominant. The
dominant motion corresponds to the scrolling of the scenery, that is
the movement of the forest relative to an observing camera.
