Title of Presentation:
New techniques for improved video coding
New ideas for improved rate-distortion efficiency of video coding beyond H.264/MPEG4-AVC are
presented. The first approach is an improvement of H.264/MPEG4-AVC encoding that optimizes
multiple pictures simultaneously. Here, significantly more computation is utilized at the encoder.
The second approach achieves improvements at the cost of increasing the computational load at the
decoder. It is based on video analysis at the encoder and decoder-based synthesis exploiting the
fact that details in highly textured areas are often ignored by the viewer. Finally, another approach
is presented that assumes the semantic knowledge of a video scene being summarized at encoder
and decoder in a computer graphic model that is animated to aid video coding.
