Description:

  In this video, we demonstrate an original approach to control camera
  position and/or lighting conditions in an environment using image
  gradient information. Our goal is to ensure a good viewing condition
  and good illumination of an object to perform vision-based task
  (recognition, tracking, etc.). Within the visual servoing framework,
  we propose solutions to two different issues: maximizing the
  brightness of the scene and maximizing the contrast in the image.
  Solutions are proposed to consider either a static light and a
  moving camera, eitheror a moving light and a static/moving camera. The
  proposed method is independent of the structure, color and aspect of
  the objects.  Experimental results on both synthetic and real images
  are shown corresponding to the experiments described in the paper.
