Abstract :
This paper presents a new method to determine efficiently the relative depth of video objects and its use for region-based interpolation. The depth is extracted by an analyse of occlusion areas of video objects along the time and the image interpolation takes into account this occlusion phenomena to increase the interpolated image quality. This region-based interpolation using relative depth of objects is very important for object-based video compression and manipulation
