Best ellipse description method of target area

Since the best description of the target is very important to the target feature, the target tracking and the target contour acquisition, a new ellipse description method is proposed. The target area was determined by the method according to the variance between the target and the background, and then the best ellipse description of the target was calculated based on the scale space theory. The experimental results show that the new method can effectively and accurately determine the demension and direction of the target area.
