Abstract

A new temporally scalable video coding algorithm based on the interpolating wavelet transform is proposed. With the proposed approach, the input video frames are first applied to an interpolating wavelet transform which generates video frames with reduced temporal redundancy in its high pass branch and original video frames at lower rate in its low pass branch. We further propose the reversible rounding method to convert the floating point coefficients given by the interpolating wavelet transform into integers without loss of resolution. The proposed video codec shares the same advantage of the traditional Temporal Subband (TSB) approach in that it is very simple in nature since it does not require the complicated motion compensation process. It outperforms substantially the TSB approach in generating lower frame rate videos.
