Abstract

A novel 3D motion compensation algorithm for the coding of 3D medical image sequences is presented. The temporal correlation existing between 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. The methods are evaluated experimentally for the coding of an 3D image sequence of a beating heart.
