| الوصف: | Multi-frame motion estimation is a new method incorporated into the video coding standard H.264/MPEG-4 Advanced Video Coding (AVC) to improve compression performances. Depending on content, the motion estimation can be short or long-term. For long-term motion estimation, the initial search point in the reference frame is important. In this paper1, we propose a new method for a fast long-term motion estimation with high definition (HD) sequences. We use an implicit uniform motion model. First we describe the multiresolution motion estimation based on spatio-temporal tubes. These tubes provide a good initial search point for the longterm motion estimation that follows. Then, the search is refined using the Nelder-Mead Simplex method. The global approach reduces computational cost and improves the accuracy of motion estimation. |
