WebJun 22, 2024 · The conventional motion compensation represents two-dimensional planar motion. This kind of motion is rarely encountered in actual videos, however, because objects move more freely and/or change their shape. For these cases, the Affine motion model was implemented in VVC that uses two or three vectors to enable motion with … WebJun 17, 2024 · Analysis of Affine Motion-Compensated Prediction in Video Coding. Abstract: Motion-compensated prediction is used in video coding standards like High …
WebThis work discovers discrete cosine basis oriented homogeneous motion regions over the current frame that can be employed to model the underlying motion field in 360-degree video frames and discovers a delta bit rate of \(5.13\%\) which can be achieved on 360- Degree test sequences, over conventional HEVC. WebApr 1, 2024 · The affine-motion model is able to capture rotation, zooming, and the deformation of moving objects, thereby providing a better motion-compensated prediction.

WebThe fundamental motion model of the conventional block-based motion compensation in High Efficiency Video Coding (HEVC) is a translational motion model. However, in the real world, the motion of an object exists in the form of combining many kinds of motions. In Versatile Video Coding (VVC), a block-based 4-parameter and 6-parameter affine …
WebMar 25, 2024 · In this paper, we propose a multi-resolution affine block-based tracker for motion estimation and compensation, compatible with existing video coding standards such as H.264 and HEVC.
