Multiresolution Motion Compensation Based on Mesh Matching

摘要

With discrete wavelet transformation(DWT) and mesh matching(MM), a new nmltiresolution video coding scheme i.s presented. Instead of DCT, DWT is performed both in intra_frame and displace frame difference(DFD) in to remove the signal correlation. Mesh matching is used to obtain high quality of motion compensation(MC). Since DWT provides a multiresolution structure, motion compensation is performed in each resolution. Progressive transmission of compressed video signal is achieved while computing time for motion compensation is reduced drastically.
