This publication goals to assemble fresh advances and functions of video coding. All chapters might be precious for researchers, engineers, graduate and postgraduate scholars, specialists during this region, and confidently additionally for those that are ordinarily attracted to video coding. The ebook comprises 9 rigorously chosen chapters. The chapters take care of complicated compression innovations for multimedia functions, bearing on fresh video coding criteria, excessive potency video coding (HEVC), a number of description coding, area of curiosity (ROI) coding, form reimbursement, blunders resilient algorithms for H.264/AVC, wavelet-based coding, facial video coding, and implementations. This e-book offers a number of worthy rules to your personal study and is helping to bridge the space among the elemental video coding thoughts and sensible multimedia purposes. we are hoping this publication is pleasing to learn and may extra give a contribution to video coding.

Inverse wavelet transforms In this step the side descriptions are inverse wavelet transformed and the two different video streams are produced. The inverse wavelet module uses the biorthogonal inverse lifting (CDF) 5/3 wavelet transform. The experimental results related to the application of MDCLVQ-A2 to MD video coding are presented in section 4. 6. 264/AVC or Motion JPEG2000 encoders. 264/AVC is selected as the video encoding standard, then the JM reference encoder is used. On the other hand, the Motion JPEG 2000 is another choice of the video encoding module that is done using the software provided by OpenJPEG library.
In the proposed MDCLVQ scheme A2 lattice points are used as the codebooks of the quantizer and the coinciding similar sublattice points are used as the labels. The schematic diagram of the MDCLVQ is illustrated in Fig. 6. The MDCLVQ scheme includes: the wavelet transformation module, the vectorization module, the LVQ module, the labeling function module, the arithmetic coder/decoder module, and the MD decoders. These modules are described in following subsections. 2. Wavelet decomposition module It is possible to consider a video as a three dimensional array in which the first two dimensions serve as spatial directions of the moving pictures, and the third dimension represents the time domain.
The double-point partitions are shown with capital letters in Fig. 5. The same partitioning scheme is repeated for every overlapping point due to the inherent symmetry of the coinciding similar sublattices. The constructed partitions are listed in Table 2. 5,3 3] Table 2. The SuperVoronoi set of the origin and their partitions for N=7. The points inside the double-point partitions are located on the boundaries of the SuperVor‐ onoi regions of the overlapping sublattice points. The points residing on the borders are always equidistant from the two adjacent overlapping points.
