sperm head meaning in Chinese

精子头部

In this paper , several different multitarget tracking algorithms are also compared , and the relationship between the maximum velocity and the concentration under the special image capture frequency is brought out . a novel tracking strategy of referring to the velocity and direction of the sperm head based on the neighbor matching technology is introduced in our algorithm
论文还分析了不同的多目标跟踪算法，给出了在特定采样频率条件下能够跟踪的目标速度和样本密度之间应该满足的条件公式，提出了适于不同条件的多因素综合的邻域匹配跟踪算法。
