No full textWe synthesized two one-dimensional compounds K2MSbS3(SH) (M = Zn, Cd) at 473 K, using thiourea as reactive flux. The compounds crystallize in the triclinic space group P (1) over bar. Their structures feature one-dimensional (1)(infinity)[M2Sb2S6(SH2)](4-) double chains along the crystallographic a axis. The (1)(infinity)[M2Sb2S6(SH2)](4-) double chains are composed of [M2Sb2S8(SH)(2)](8-) eight-membered rings. Similar band gaps of the two compounds, E-g = 2.75 eV for K2ZnSbS3(SH) and E-g = 171 eV for K2CdSbS3(SH), were obtained from optical absorption measurements, which are consistent with theoretical calculations. The analysis of density of states indicates that the valence band maximum and conduction band minimum consist mainly of S-3p orbitals and Sb-5p orbitals, respectively.National key research and development program [2016YFB0901600]; Chinese Academy of Sciences [KJCX2-EW-W11, XDB04040200]; NSF of China [61376056, 51402335, 11404358]; Science and Technology Commission of Shanghai [13JC1405700, 14520722000]SCI(E)[email protected]; [email protected]

Coding mode determination using fuzzy reasoning in H.264 motion estimation
No full text[[abstract]]Exhaustively searching over all possible partition modes using rate distortion comparison in H.264/AVC motion estimation to choose the best coding mode for each macroblock has much better coding efficiency than other existing standards. However, exhaustive searching has high computational complexity. This study analyses the statistics of coding mode distribution to determine the need of motion estimation for a current macroblock according to its previous corresponding macroblock information. A fast algorithm based on fuzzy reasoning with temporal and texture correlation of coding block information is proposed to reduce the computation time effectively. The fuzzy reasoning technique is used to determine the most appropriate mode quickly for motion estimation in H.264/AVC video coding. Simulation results show that the proposed algorithm has an encoding time 55.7-70% less than that of taken by searching for all coding modes exhaustively, while retaining the almost same coded picture quality and bit rate.[[note]]SC
