摘要
精子质量的优劣是评价男性生殖能力的重要指标.根据世界卫生组织(WHO)人类精液检查与处理实验室手册第5版可知,对精子序列图像进行超长时间跟踪可以更精确地分析精子的质量.本文根据精子运动的特点,提出一种基于小窗口的应用于超长时间精子序列图像跟踪的最大距离预测法.该方法可跟踪精子在每一帧的轨迹点,然后把这些轨迹点坐标连在一起就是精子的运动轨迹.试验结果表明:该方法可以快速、准确、稳定地实时跟踪精子.
Sperm quality is an important index of male reproductive ability. Acrroding to the request of laboratory manual version 5 of human semen examination and processing from the world health or- ganization （WHO）, a method of ultra-long time tracking on sperm sequence images can more accu- rately analyze the quality of sperm. According to the characteristics of sperm moving target, we pr- esent a method of the maximum distance prediction based on a small window to track ultra-long time sperm sequence images. By tracking sperm track points of each frame, then putting these track point coordinates together ,the trajectory of sperm is obtained. Experimental results show that the method can fastly, accurately and stably conduct the real-time tracking of sperm.
