Purpose of HYAT solid insulated filled cable: solid insulated filled cable is suitable for the urban telecommunication line of the local telecommunication network in the town of wuyu, and also for the special network line connecting to the public network. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shield layer are filled with oil paste and poured to prevent water intrusion. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter 0. 32, 0. 40, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 (mm). Insulating material: high density polypropylene or polypropylene, colour of the insulated wire as indicated by full chromatograph. Pair of insulated wires: twist two different colored insulated wires into pairs at different pitch and use the specified chromatographic combination to identify pairs. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. Core tape: wrap with a polygrease film tape. Shielding: metal strip with or without striping, which is longitudinal wrapped outside the core of the cable. Sheath: black low density polymer. Double sheathed cables can also be provided. Identification and marking: cable outer surface sexual identification mark, mark at no more than alternate 1 m intervals, tag contents are: the diameter of wire, line number, cable type, factory name and year of manufacture, marking at no more than alternate 1 m intervals to mark on the surface, but with the tag stagger.

运动目标跟踪运动目标的跟踪，即通过目标的有效表达，在图像序列中寻找与目标模板最相似候选目标区位置的过程。简单说，就是在序列图像中为目标定位。运动目标的有效表达除了对运动目标建模外，目标跟踪中常用到的目标特性表达主要包括：视觉特征(图像边缘、轮廓、形状、纹理、区域)、统计特征(直方图、各种矩特征)、变换系数特征(傅里叶描绘子、自回归模型)、代数特征(图像矩阵的奇异值分解)等。除了使用单一特征外，也可通过融合多个特征来提高跟踪的可靠性，目前主流的方法有：基于区域匹配跟踪算法、基于轮廓匹配跟踪算法、基于特征匹配跟踪算法。
