Abstract :
The paper presents a method for an automatic extraction of relative depth of objects in monocular video sequences. Video sequences are represented as a 2D and 1/2 combination of plane objects corresponding to video object plans (MPEG4) with associated affine motion. The method is based on the the analysis of integral profile of the grey-level function of objects which is computed by a discrete version of Radon transform
