The title complex[Cu(C12H8N2)(C10H11NO5S)]·3.5H2O was synthesized by Taurine o-vanillin schiff base,O-phenanthroline and copper(II)acetate monohydrate in ethanol solution and the crystal structure was determined ...The title complex[Cu(C12H8N2)(C10H11NO5S)]·3.5H2O was synthesized by Taurine o-vanillin schiff base,O-phenanthroline and copper(II)acetate monohydrate in ethanol solution and the crystal structure was determined by X-ray diffraction method.The crystal belongs to Monoclinic system,space group P2(1)/c,with cell parameters:a=14.9320(10),b=26.6371(17),c=13.1937(9),β=114.0320(10)°,V=4792.8(6)3.The copper(II)atom is coordinated by two N atoms from one O-phenanthroline molecule,two O atoms from a Taurine o-vanillin schiff base and one N atom from this schiff base,resulting in a square-pyramid geometry.The packing diagram shows that a three-dimensional network is formed via hydrogen bonds and π-π stacking interactions.展开更多
文摘为了解决基于区域的平面物体跟踪方法容易陷入局部最优的问题,提出一种基于快速顶点漂移的平面物体跟踪方法.首先,构造包含不同尺度下的图像和物体区域采样点集合的金字塔结构;其次,在不同尺度下使用快速顶点漂移方法,利用全局的相似性度量函数迭代求解最优的顶点偏移,得到跟踪结果.在平面物体跟踪数据集POT上的实验结果表明,该方法在不同场景下平均跟踪准确率可达49.65%,平均高出其他参与测试的基于区域的方法31.87个百分点,平均每帧跟踪时间为0.12 s.
