摘要： Provided is system and a method of producing a high definition video from a low definition video. According to one or more embodiments, the method performs a trajectory estimation and a matching operation only with respect to a feature region pixel of a previous frame of the low definition video, which is different from all pixels of the previous frame, thereby reducing an amount of computation to improve efficiency of a memory, producing the high definition video in real time, and producing a more accurate high definition video with respect to a feature region.
