摘要
Mesh-Based model offers a lot of functionalities that the Block-Based model does not offer. While the Mesh-Based modes are suitable for spatially continuous representation of in-plane rotations, zooms, and other motions that can be represented by parametric mappings, the Block-Based models peform better around motion boundaries. Therefore, a hybrid codec with Block-Based and Mesh-Based modes, which nicely complement each other, yields the best results over a wide range of video at low bitrates. This paper presents a low-power motion compensation architecture for video applications. It extends the traditional Block-Based video coders to incorporate the Mesh-Based model. Using a modified affine transform that reduces the complexity of the motion compensation also reduces the computational cost.
