Abstract :
A novel motion compensation algorithm for the coding of 3D image sequences is presented. The temporal correlation existing between two successive in time 3D data sets is exploited using a 3D cube matching algorithm (CMA). In order to cope with more complex motions and to adapt compensation to the high activity regions, a 3D warping based motion estimation technique is introduced. Simulation results are given for the 3D medical image sequence "Beating Heart".
