设计了一种新的真核生物鞭毛和纤毛弯曲的数字图像分析方法。在分析系统中，所有图像像素被系统地提取和处理，以测量角方向和曲率。通过对鞭毛理论模型图像的正弦弯曲波和圆弧-直线弯曲波的模拟实验，表明该方法具有较高的精度。然后，这种方法揭示了突变的曲率在精子鞭毛和胚胎纤毛的海胆，Hemicentrotus pulcherrimus的斜率。这表明，数字图像处理技术可能有助于鞭毛和纤毛运动的研究。
A novel method of digital image analysis of the bends of eukaryotic flagella and cilia was devised. In the analysis system, all image pixels were systematically extracted and processed to measure angular direction and curvature. Simulation experiments on theoretical model pictures of flagella with sine-generated or arc-straight line bending waves demonstrated that the method can be used with considerable high accuracy. This method then revealed abrupt changes in slope of the curvature in sperm flagella and embryo cilia of the sea urchin, Hemicentrotus pulcherrimus. This indicates that the digital image processing used may be helpful in the study of flagella and ciliary movements.
