Abstract

This article deals with 3D scene analysis for coding purposes and is part of general research in 3D television. The method proposed here attempts, through dynamic monocular analysis, to estimate three-dimensional motion and to determine the structure of the observed objects. Motion and structure estimation is achieved by means of a differential method. Images are segmented according to spatio-temporal criteria, using a hierarchical method of quad-tree type with overlappings. Segmentation and estimation are performed jointly.
