Abstract

In this paper, we address the problem of structuring video documents into meaningful spatio-temporal entities, involving the tracking of spatio-temporal zones of interest. We present a newte chnique for tracking over time a region in the image which is initially user-delimited. The tracking method is based on the robust estimation of a 2D affine motion. In order to facilitate the task of the user, the scheme includes the original idea of an automatic tracking failure detection procedure which exploits at lowcost information related to the estimated motion model. Experimental results are provided on excerpts of a real movie.
