3D based video coding in the overcomplete discrete wavelet transform domain with reduced delay requirements

In this work, we propose a new temporal filter set to minimize delay in 3D wavelet based video coding, which gives a performance at par with existing longer filters. Our filter set will not have any boundary effects at the group of frames (GOF). The length of the GOF can vary from five to any number of frames depending on delay requirements. We also propose a novel technique of assigning priorities to temporal subbands at different levels to control distortion fluctuation inside a GOF. Experimental results are presented and conclusions are drawn.
