Energy distributed update steps(edu) in lifting based motion compensated video coding
Subband video coding is an elegant scheme to fulfill high performance scalable video coding. In this paper, a new update scheme, energy distributed update steps(EDU), is proposed for the temporal transform in lifting based motion compensated video coding. The idea is to update where predict is made by distributing high-pass signals to the low-pass frame. The scheme avoids complex and inaccurate inversion of the motion information that used in the traditional update steps, thus it reduces computations in temporal transform. Experimental results show that the coding performances can be improved up to 0.77dB.
