Motion Estimation Method using the Spatio-Temporal Characteristics of Moving Objects

This paper presents a motion vector detection method which takes account of the spatio-temporal continuity of motion vectors and the local characteristics of pictures. First, we discuss a method for tracing motion vector trajectories to assess the spatio-temporal 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. The 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.
