Abstract
Disclosed is a method for the detection of the relative depth of two neighboring regions in relative motion with respect to each other in two images obtained from different shots of a scene, in order to know the composition of the scene. The method consists in carrying out a spatial segmentation of one of the images, called a reference image; a local estimation of the motion between the two images, the resultant vector field of which is called local motion; a determining of the motion estimation errors along the motion boundaries; and an analysis of the localization of the motion estimation errors along the motion boundaries to conclude that a region A is in front of a region B when the motion estimation error along the boundary is chiefly localized on the side B of this boundary.
