This paper presents a simple and fast method for unsuper-vised trajectory estimation of multiple moving objects within a video scene. It is entirely based on the motion vectors that are present in compressed H.264/AVC or SVC video streams. We extract these motion vectors, perform robust frame-wise global motion estimation and use these estimates to form(More)
In this paper we propose a video-object based coding scheme using dynamic coding. The principle of dynamic coding is to set on competition different coders on each video object. Thus, we are proposing a video-object based dynamic coding scheme using four completely different coders. The novelty of our work firstly comprise a global rate-distortion(More)
