Abstract
In this paper, we present a compact survey of bit-rate control techniques which can be used in design of video codecs equipped with online information on dynamical ROIs. We introduce the concept of zero rate increment on level sets in the context of linear data source models in ñ-domain. This approach enables a smooth image fidelity degradation on level sets for distance function from pixel to ROI.We focus in our examples on H.264/AVC which is the state-of-the-art in the video codec area.
