| Title | Camera Motion-Constraint Video Codec Selection |
| Invited? | Yes |
| Abstract | In recent years advanced video codecs have been developed, such as standardized in MPEG-4. The latest video codec H.264 /AVC provides compression performance superior to previous standards, but is based on the same basic motion compensated -DCT architecture. However, for certain types of video, it has been shown that it is possible to outperform the H.264/ AVC using an object-based video codec. Towards a general- purpose object-based video coding system we present an automated approach to separate a video sequences into subsequences regarding its camera motion type. Then, the subsequences are coded either with an object-based codec or the common H.264/AVC. Applying different video codecs for different kinds of camera motion, we achieve a higher overall coding gain for the video sequence. In first experimental evaluations, we demonstrate the excellence performance of this approach on two test sequences. |
