Abstract

This paper presents the performance of the hierarchical adaptive structured mesh (HASM). HASM can be used for limited power and limited bandwidth applications since it reduces the power consumption and the required bandwidth. The proposed technique can be used in MPEG-4 applications. The encoder generates the mesh using HASM and estimates the motion vectors for the mesh nodes, then it sends the mesh code and the nodes´ motion vector to the decoder. The decoder uses the mesh topology and the nodes´ motion vector to predict the frame by tracking the deformation of the mesh. The performance analysis is conducted and it shows that HASM outperforms the unstructured mesh techniques since it reduces the mesh code and reduces the power consumption for the receiver
