“…3D wavelet transforms have also been investigated as a method for video compression (Sampson et al, 1995;Lee et al, 1997b;Beong and Pearlman, 1997;Vass et al, 1998;Lin and Liu, 1999;Bernabe et al, 2000;Lazar and Averbuch, 2001;Seigneurbieux and Xiong, 2001). Research in 3D Sub-Band Coders (SBC) uses wavelet transform in the temporal axis which significantly reduces computation and design complexity and provides better compression performance than current block-based motion compensated predictive methods.…”

The proposed method consists on '3D-to-2D' transformation of the temporal frames that allows exploring the temporal redundancy of the video using 2D transforms and avoiding the computationally demanding motion compensation step. This transformation turns video spatial temporal correlation into high spatial correlation. In this paper, we explore the proposed method performances and try to better show what it actually offers to users. The paper presents also the extensions chosen to reduce the perceived artefacts and increase the perceptual as well as objective (PSNR) decoded video quality, which is actually competitive with state-of-the-art video coders, especially when operating complexity is taken into account.Reference to this paper should be made as follows: Ouni, T., Ayedi, W. and Abid, M.

“…Kim and Pearlman proposed to extend SPIHT to 3-D subband video coding [27], and results superior to MPEG-2 were reported. Recently, Vass et al applied the SLCCA data organization and representation strategy for low computational complexity, highly scalable video coding [28]. In Sarnoff Corp.'s zerotree entropy (ZTE) [16] video coder, after time-domain block-based motion estimation and motion compensation similar to that of H.263, an EZW variant algorithm was proposed for the representation and encoding of motion compensated error frames.…”

In recent years, a tremendous success in wavelet image coding has been achieved. It is mainly attributed to innovative strategies for data organization and representation of wavelet-transformed images. However, there have been only a few successful attempts in wavelet video coding. The most successful is perhaps Sarnoff Corp.'s zerotree entropy (ZTE) video coder. In this paper, a novel hybrid wavelet video coding algorithm termed video significance-linked connected component analysis (VSLCCA) is developed for very low bit-rate applications. There also has been empirical evidence that wavelet transform combined with those innovative data organization and representation strategies can be an invaluable asset in very low bit-rate video coding as long as motion compensated error frames are ensured to be free of blocking effect or coherent.In the proposed VSLCCA codec, first, fine-tuned motion estimation based on the H.263 Recommendation is developed to reduce temporal redundancy, and exhaustive overlapped block motion compensation is utilized to ensure coherency in motion compensated error frames. Second, wavelet transform is applied to each coherent motion compensated error frame to attain global energy compaction. Third, significant fields of wavelettransformed error frames are organized and represented as significance-linked connected components so that both the withinsubband clustering and the cross-scale dependency are exploited. Last, the horizontal and vertical components of motion vectors are encoded separately using adaptive arithmetic coding while significant wavelet coefficients are encoded in bit-plane order by using high order Markov source modeling and adaptive arithmetic coding.Experimental results on eight standard MPEG-4 test sequences show that for intraframe coding, on average the proposed codec exceeds H.263 and ZTE in peak signal-to-noise ratio by as much as 2.07 and 1.38 dB at 28 kbits, respectively. For entire sequence coding, VSLCCA is superior to H.263 and ZTE by 0.35 and 0.71 dB on average, respectively.

“…Unfortunately, most of the existing 3-D zerotree codecs do not consider the structure of the tree systematically. A commonly used tree is the symmetric 3-D tree [4], [11], [13], [17], [19], [20], [28]. The performance of the symmetric 3-D tree is not optimal because the properties of the video signal and the wavelet coefficients are not symmetric along all three dimensions.…”

Optimal 3-d coefficient tree structure for 3-d wavelet video coding

An optimal three-dimensional (3-D) coefficient tree structure for 3-D zerotree wavelet video coding is considered in this paper. The 3-D zerotree wavelet video coding is inspired by the success of the two-dimensional (2-D) zerotree wavelet image coding. Existing 3-D zerotree wavelet video codecs use the either symmetric or symmetric-alike 3-D tree structure, which is a straightforward extension of the symmetric 2-D tree structure in the zerotree wavelet image coding. In this paper, we show that the 3-D zerotree coding does not need to be applied symmetrically along all the directions, as the 2-D zerotree image coding does. We find that an asymmetric 3-D tree structure working with a more flexible asymmetric 3-D wavelet transform can produce a higher compression ratio than traditional symmetric approaches. The new 3-D tree structure can be used to improve the rate-distortion performance of many existing 3-D zerotree wavelet video codecs without sacrificing other features such as scalability and computational efficiency. The new tree structure is applied to the 3-D set partitioning in hierarchical trees method and receives convincing peak signal-to-noise ratio improvements in experiments. Index Terms-Set partitioning in hierarchical trees (SPIHT), symmetric and symmetric-alike three-dimensional (3-D) tree structure, 3-D zerotree coding, video compression, wavelet transform.
