This paper proposed an algorithm based on mathematical morphology.It consists of four same-parity fields motion estimation,mathematical morphology operation, and robust processing.It estimated the motion by comparing the sum of absolute block difference(SAD) between same-parity 4-field with threshold of motion.And there was a morphological operation on motion vectors that can reduce the high-frequency noise greatly.The proposed method can obtain quite good display quality and has been embedded in the chip of digital video process(DVP) which is manufactured with 0.18 μm CMOS process.
