Extending hevc by an affine motion model
WebHEVC, short for (High Efficiency Video Coding) is a video codec for encoding/decoding high quality videos at lower bitrates. Note that HEVC is not a filename extension. Rather, it is … WebJul 1, 2014 · For non-translational motion the translational model leads to high data rate due to inaccurate prediction. Although an affine motion model can describe non-translational motion, the data rate of its additional parameters is often larger than the data rate reduction achieved by more accurate prediction, especially if small blocks are used.
