Variable transform block (TB) sizes cause high computational complexity at the HEVC encoder. In this paper, a fast residual quad-tree (RQT) structure decision method is proposed to reduce the number of candidate transform sizes. The proposed method uses spatial and temporal correlation information in the neighbor blocks to predict the depth of current RQT. In addition, an efficient all zero block...
Dry and wet deposition of inorganic nitrogen species were monitored at one urban (SDS) and one rural (TFS) site during September 2009 and August 2010 at Urumqi in a semi-arid region. Atmospheric concentrations of NH3, NO2, HNO3, particulate ammonium and nitrate (pNH4+ and pNO3-) concentrations and NH4-N and NO3-N concentrations in precipitation showed large monthly variations and averaged 7.0, 18...
With the development of information processing technology, DCT has been used more and more widely and the research on DCT algorithm is very much too. But the physical performance of DCT is unclear. To overcome such drawbacks, the paper has proposed 1-D SDCT operation method. First, some new 1-D matrix operation principles are defined. Then, the transform basic matrix used for 1-D SDCT operation was...
In view of the characteristics of Web environment and Web service, capability, security and reputation are imported as trust attributes for Web service to generate trust degrees. Membership degree, non-membership degree and intuitionistic index are used to describe trust attributes. Calculation formulas of trust contribution degree of capability, security and reputation are proposed. On the basis...
