Abstract

A METHOD FOR MOTION ESTIMATION INCLUDES STEPS FOR CONSTRUCTING A FIRST IMAGE SEGMENT REPRESENTING A PORTION OF PRESENT IMAGE FRAME AND A SECOND IMAGE SEGMENT HAVING A PLURALITY OF IMAGE SEGMENTS OF AN ADJACENT FRAME, COMPARING SAID PLURALITY OF IMAGE SEGMENTS OF SAID SECOND IMAGE SEGMENT WITH THE IMAGE SIGNAL WITHIN THE FIRST IMAGE SEGMENT, AND GENERATING A NUMBER OF ERROR VALUES, DETECTING A FIRST MOTION VECTOR AT ONE SCALE OF RESOLUTION USING THE GENERATED ERROR VALUES, OUTPUTTING THE ERROR VALUE ASSOCIATED WITH A REFERENCE SEGMENT POINTED BY THE FIRST MOTION VECTOR, AND THE ERROR VALUES CORRESPONDING TO THE REFERENCE SEGMENT SHIFTED BY ONE UNIT OF SELECTED RESOLUTION RESPECTIVELY IN SELECTED DIRECTION(S), GENERATING A SECOND MOTION VECTOR IN FINER SCALE OF RESOLUTION USING THE OUTPUT ERROR VALUES, AND SUMMING THE FIRST AND SECOND MOTION VECTORS.
