Mesh-Based model offers a lot of functionalities that the Block-Based model does not offer.While the Mesh-Based modes are suitable for patially continuous representation of in-plane rotations,zooms,and other motions that can be represented by parametric mappings,the Block-Based models perform 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 .
