摘要： A method of calculating discontinuity of a motion vector includes obtaining at least any one of a k-th projected forward motion vector by a forward motion vector of a block and a k-th projected backward motion vector by the forward motion vector and at least any one of a k-th projected forward motion vector by a backward motion vector and a k-th projected backward motion vector by the backward motion vector; obtaining inconsistency of forward motion vector to k-th frame projection and inconsistency of backward motion vector to k-th frame projection by calculating a first difference function using the obtained vectors, and calculating discontinuity using the inconsistency of forward motion vector to k-th frame projection and the inconsistency of backward motion vector to k-th frame projection.

摘要： A fallback performing method including: calculating unreliability of a motion vector in a block included in a moving object in two frames classified in terms of time; calculating discontinuity of the motion vector for a predetermined time; calculating a fallback level from the unreliability and the discontinuity; and performing fallback based on the calculated fallback level.

摘要： Provided are a method for motion estimation and an apparatus for processing an image. The method includes extracting a pattern from any one frame, classifying the extracted pattern as any one of predetermined basic patterns, counting basic patterns of regions included in macroblocks according to types of the basic patterns to set representative basic patterns of the macroblocks, calculating at least one of a sum of absolute difference (SAD) term coefficient and a smoothness constraint (SC) term coefficient from a correlation between representative basic patterns of macroblocks included in a macroblock group, and calculating a cost function result using at least one of the calculated SAD term coefficient and SC term coefficient.
