虽然不同的光流技术不断出现，但一直缺乏对现有方法的定量评估。对于一组常见的真实的和合成图像序列，我们报告的结果，一些经常引用的光流技术，包括差分，匹配，基于能量的实例，和基于相位的方法。我们的比较主要是经验性的，并集中在速度测量的准确性，可靠性和密度;他们表明，我们实现的技术之间的性能可以显着不同。
While different optical flow techniques continue to appear, there has been a lack of quantitative evaluation of existing methods. For a common set of real and synthetic image sequences, we report the results of a number of regularly cited optical flow techniques, including instances of differential, matching, energy-based, and phase-based methods. Our comparisons are primarily empirical, and concentrate on the accuracy, reliability, and density of the velocity measurements; they show that performance can differ significantly among the techniques we implemented.
