A Multiresolution Block Matching Technique for Image Motion Estimation

This paper discusses a new multiresolution block matching technique. Unlike previously known techniques, this method estimates motion bottom-up so that approximate motion information from a high resolution is refined by the information from lower resolutions. Our experiment on real image sequences to which various levels of noise were added showed that this method performs better than other existing top-down techniques. It has been tested as part of a simple DCT codec, not described in this paper because of space constraints. A similar performance improvement over other techniques was observed.
