Affine motion compensation
WebAug 24, 2024 · In this paper, we propose a deep affine motion compensation network (DAMC-Net) for inter prediction in video coding to effectively improve the prediction accuracy. To the best of our knowledge, our work is the first attempt to deal with the … WebAug 3, 2024 · Some examples of VVC also provide an affine motion compensation mode, which may be considered an inter-prediction mode. In affine motion compensation mode, video encoder 200 may determine two or more motion vectors that represent non-translational motion, such as zoom in or out, rotation, perspective motion, or other …

WebMar 27, 2013 · The affine-motion model is able to capture rotation, zooming, and the deformation of moving objects, thereby providing a better motion-compensated prediction. However, it is not widely used due to difficulty in both estimation and efficient coding of its motion parameters. To alleviate this problem, a new control-point representation that … WebUnder the affine prediction mode, a CU may be split into multiple 4×4 PUs for prediction. Motion vectors may be derived for each 4×4 PU and motion compensation may be performed accordingly on the 4×4 PU. Under the ATMVP mode, a CU may be split into one or multiple 8×8 PUs for prediction. Motion vectors are derived for each 8×8 PU and ...

WebAffine warping in two shears likelihood of the current block having a particular MV as a canddiate. To code a MV, AV1 signals the index of a selected reference MV from the list, followed by encoding a delta if needed. In practice, the combination of the reference MV and the delta is signaled through modes, as in VP9. WebAffine motion compensation (AMC) is a promising coding tool in Joint Exploration Model (JEM) developed by the Joint Video Exploration Team. AMC in JEM employs a 4 …
