IMAGE SEARCH METHOD FOR REDUCING COMPUTATIONAL COMPLEXITY OF MOTION ESTIMATION

摘要

image retrieval method for fast motion estimation as described herein , to determine the sign of the predicted motion vector step , the predicted using the motion vector calculating the slope of each of the first slope and the first reference frame, the previous reference frame of the reference frame of the second reference frame , the sign of the calculated slope of the determined motion vector in response to the size of the area to be asymmetric Hexagon determining search is performed , performing the asymmetric Hexagon search for the determined area , and the search result with the asymmetric Hexagon compares a predetermined threshold asymmetric Hexagon Search a step of determining whether or not to end .
