This paper presents a motion vector detection method that takes into account the spatiotemporal continuity of motion vectors and the local characteristics of pictures. First, we discuss tracing motion vector trajectories to assess the spatiotemporal continuity of motion vectors and a method of motion vector detection using motion vector reliability. Next, we explain a motion vector estimation method in which the local characteristics of pictures are considered. This method consists of the removal of erroneously detected motion vectors by use of the luminance correlation of pictures to assign detected vectors. In conclusion, it is shown by simulation that these methods produce beneficial results for the improvement of motion vector detection.
