Advanced Video Coding for Next-Generation Multimedia by Yo Sung Ho

By Yo Sung Ho

This e-book goals to assemble fresh advances and functions of video coding. All chapters will be invaluable for researchers, engineers, graduate and postgraduate scholars, specialists during this zone, and confidently additionally for those that are quite often attracted to video coding. The booklet comprises 9 conscientiously chosen chapters. The chapters care for complex compression recommendations 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 repayment, mistakes resilient algorithms for H.264/AVC, wavelet-based coding, facial video coding, and implementations. This publication presents a number of worthy principles on your personal learn and is helping to bridge the distance among the fundamental video coding suggestions and useful multimedia purposes. we are hoping this publication is agreeable to learn and may additional give a contribution to video coding.

The corresponding (15) For example, with α = - 3 and β = 2, a clean similar sublattice of the hexagonal lattice with index N = ( - 3)2 - (-3)(2) + (2)2 = 19 is generated. 5i 3. 5 3 Figure 2. The geometrically similar sublattice of A2 with index N=19 generated by Eq. (16). It is also possible to calculate the index of the sublattice generated by Gi' using Eq. (13). The determinant of the generator of the hexagonal lattice at unit scale is 3 / 2. 5) × ( 3) = 19 3 / 2. Thus, the index will be ' (19 3 / 2) / ( 3 / 2) = 19.

The necessary shift to translate adto the original lattice point is also t = (7,0). 734). The decoding procedure is depicted in Fig. 6. However, assume that one of the descriptions is lost and therefore only one description is received correctly. As the labeling function is balanced, it does not matter which label is received. In case λ'1 is received, it is processed by the side decoder 1 to find the approximate point. 5 3 and its equivalent sublattice ˜e = 1. point that is residing within Ssv (O ) is given by λ Figure 6.

2. Elementary of lattices In mathematics (algebra), a lattice is defined as a partially ordered set (poset) in which any two elements have a unique supremum (the element’s least upper bound or join) and an infimum (greatest lower bound or meet). In other words, a lattice is considered as a subset of points in the Euclidean space that share a common property. For example the lattice An is a subset of 23 24 Advanced Video Coding for Next-Generation Multimedia Services Figure 1. A general scheme of the MD coding scheme.
