Paper Abstract

Registration is a problem of motion estimation (ME). The conventional ME methods often can not trade off between the estimation precision and computational complexity. This proposed method based on wavelet transform is a multi-scale block matching one, which takes the full advantage of the self-similarity that occurs after the wavelet transforming. The precision is from coarse to fine, which accelerates the matching procedure and reduces the computation consumption noticeably. This multi-scale registration algorithm has been proved practicable and useful in the real application.
