Abstract

A METHOD FOR ESTIMATING THE MOTION OF A MOVING PICTURE USING A TWO-DIMENSIONAL TRIANGLE-PATCH WIREFRAME MODEL IS PROVIDED.THE METHOD FOR ESTIMATING THE MOTION OF THE MOVING PICTURE ACCORDING TO THE PRESENT INVENTION INCLUDES THE STEPS OF DIVIDING THE CURRENT FRAME OF AN INPUT IMAGE SIGNAL INTO N1XN2 MACROBLOCK UNITS, DIVIDING EACH OF THE MACROBLOCKS INTO TWO TO CREATE TRIANGLE PATCHES, CALCULATING PIXEL DIFFERENCES BETWEEN A REFERENCE BLOCK AND SEARCH BLOCKS OF THE PREVIOUS FRAME FRAME A PREDETERMINED RANGE ON THE BASIS OF THE COORDINATE VALUES OF THE RESPECTIVE APEXES OF THE TRIANGLE PATCHES, AND CALCULATING A MOTION VECTOR OF THE REFERENCE BLOCK OF THE CURRENT FRAME FROM THE COORDINATE VALUE OF THE MATCHING BLOCK OF THE.PREVIOUS FRAME HAVING A MINIMUM PIXEL DIFFERENCE VALUE AMONG, THE CALCULATED PIXEL DIFFERENCES. THEREFORE, ACCORDING TO THE ABOVE METHOD, IT IS POSSIBLE TO OBTAIN A PICTURE OF GOOD QUALITY COMPARED WITH A PICTURE RECONSTRUCTED BY THE CONVENTIONAL BMA METHOD FOR ESTIMATING THE MOTION.
