Paper Abstract

The extension of conventional video coding schemes by additional content-based functionalities is a key issue in MPEG-4 standardization. To this end, suitable techniques for coding texture information of arbitrary shaped image segments have to be developed. In this paper, a new approach for coding of such image segments is presented which is based on signal extrapolation. In contrast to other extrapolation approaches described in the literature, the proposed method is computationally simple and specifically adapted to the needs of real-time video coding. The extrapolation works in the spatial domain and yields a signal with high energy concentration in the low frequency area. Restricting the extrapolation to a block grid allows straight forward extension of common block-based video coding techniques to coding of arbitrarily shaped image objects.
