摘要：

We investigate the effect of different tracking strategies, such as local and full-field tracking, on the mean and variance of the image velocity field. We show that while local tracking reduces the velocity variability in an eccentricity-dependent manner, full-field tracking reduces velocity variability equally across the image. We test our predictions with digitized image sequences.
