编码性能是通过与原始EVC编码器比较Bjøntegaard delta rate(BD-rate)和编码节省时间(time saving,TS)来衡量的。每个序列的TS是由四个不同QP的平均TS计算出来的,TS用来表示复杂度的降低,其计算方法是: (6) 式中:TETM为原算法的总编码时间,Tpro为本文所...
该算法在VVC测试模型VTM-4.0-360Lib-9.0中实现。360个测试序列在通用测试条件下使用全intra配置进行编码,QP值分别为22、27、32和37。使用BDBR、省时的ΔTS和BDPSNR来评估算法的性能。ΔTS的定义如下。$$\DeltaTS(\%)={1}{4}和限制{{{T_{VTM}(i) 其中(T_{VTM}(i)\)和(T_{p}(i)\)分别表示参考V...

parentCTU是当前待编码的父CU,CuGeom是表达划分四叉树的数据结构,qp是量化参数(Quantization Parameter)。 处理流程 不同版本的编码器在该部分的处理流程基本一致,都可以分为四步: 初始化传入参数到当前命名空间的变量; 计算父CU的率失真损失,即划分前的率失真损失; ...
Angle-resolved photoemission spectroscopy using tunable low energy photonsallows us to study the quasi-particle (QP) dispersions of the inner and outerCuO2 planes (IP and OP) separately in the tri-layer cuprateBi$_2$Sr$_2$Ca$_2$Cu$_3$O$_{10+\\delta}$ (Bi2223). The kink energy of...

Direct solar-driven methane (CH4) reforming is highly desirable but challenging, particularly to achieve a value-added product with high selectivity. Here, we identify a synergistic ensemble effect of atomically dispersed copper (Cu) species and partiall
QP can affect the spatial details of CU partitioning and partitioning results. The larger the QP, the larger the CU partition size; the smaller the QP, the smaller is the CU partition size. (5) The difference between the predicted partition depth and the real depth of the current CU (...
Their algorithm is based on the observation that, with the increase in the QP value, the chances of CU splitting decrease. The aforementioned works are nice efforts in the domain of MV-HEVC. However, we observed that still, many aspects of the correlation between the splitting and mode ...
