Abstract
Measures for a motion compensation are combined with an image segmentation in four modes. In a first mode, a current picture is image-segmented before an estimation of a relative motion between a segmented region of the current picture and a corresponding region of a reference picture. In a second mode, a relative motion is estimated between a minute piece of a current picture and a corresponding minute piece of a reference picture, to be employed as a character parameter for an image segmentation. In a third mode, a relative motion is estimated between a sub-region of an image-segmented region and a corresponding small region, to be employed as a character parameter for a resegmentation. In a fourth mode, a relative motion between minute pieces is estimated to provide an additional character parameter for an image segmentation to be performed on a current picture, before a reestimation of a relative motion between an estimated region and a corresponding region.
