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. We propose three modifications to traditional motion compensation techniques in video coding standards such as H.264 and HEVC. First, we replace … 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 …
WebDec 14, 2024 · This study proposes a lightweight solution to estimate affine parameters in affine motion compensation. Most of the current approaches start with an initial approximation based on the standard motion estimation, which only estimates the translation parameters. From there, iterative methods are used to find the best … WebJul 8, 2024 · An example of the 6-parameter affine motion model. where MV 0 , MV 1 and MV 2 are MVP candidates that belong to the tuples S 0 , S 1 and í µí± í µí± 2 .
