INVESTIGATION OF MOTION-COMPENSATED LIFTED WAVELET TRANSFORMS
Markus Flierl, Bernd Girod · 2003
This paper investigates lifted Wavelet transforms applied in the temporal direction of a video sequence. Due to the motion between pairs of frames, motion compensation is utilized in the lifting steps. We discuss the modified Haar and 5/3 Wavelet kernel and provide experimental results for dyadic decompositions with various levels. Further, we utilize a signal model for a theoretical discussion of both kernels. We generalize and replace the dyadic decompositions by the Karhunen-Loeve Transform in order to provide theoretical performance bounds for the compression efficiency of these coding schemes.
