Variable temporal length 3D DCT-DWT based video coding
2007
2007 International Symposium on Intelligent Signal Processing and Communication Systems
Almost all variable length 3D-DCT algorithms employ thresholds. Although the selection of threshold considerably affects the algorithm performance, there is no framework to choose them effectively. This paper proposes a hybrid transform for 3D-DCT based video coding. In the proposed model, 3D-DCT and discrete Haar transform are iteratively used to remove the redundancy for each cube and thus an adaptive scheme is derived to realize variable temporal length of DCT implementations.
