Paper Abstract

The article deals with 3D scene analysis for coding purposes and is part of general research into 3D television. The method proposed here attempts, through dynamic monocular analysis, to estimate three-dimensional motion and determine the structure of the observed objects. Motion and structure estimation are achieved by means of a differential method. A multipredictor scheme is used to guarantee correct initialisation of the algorithm. Images are segmented according to spatio- temporal criteria, using a hierarchic method based on a quad-tree with overlapping. Segmentation and estimation are performed jointly.
