In this paper we present a scene-based video watermarking scheme using support vector machines (SVMs). In a given scene, the algorithm uses the first h′ frames to train an embed...

In this work, we propose a novel fragile watermarking scheme in wavelet transform domain, which is sensitive to all kinds of manipulations and has the ability to localize the tamp...

We propose a novel data embedding scheme for H.263 video coding. The proposed method, which can protect important information such as picture header and motion vector, is specific...

This paper contains two contributions to very-low-bitrate video coding. First, we show that in contrast to common practice incremental techniques for rate-distortion optimization ...
