Temporal interpolation using wavelet domain motion estimation and motion compensation

Abstract

Temporal frame subsampling is a simple but efficiency technique to achieve very high compression ratio in slow motion video. The discrete wavelet transform (DWT) is successful in still image compression and many researchers try to extend the usage of DWT to a video coder. In this paper, we incorporate these two ideas, together with the newly developed wavelet domain motion estimation method - low-band-shift motion estimation (LBSME) to develop a novel temporal interpolation scheme in the wavelet domain.
