Abstract
A method and system are provided for focusing an imaging device on a liquid sample flowing through a field of view of the imaging device. Objects are segmented in the captured frames and used to account for the fact that the sample is flowing. Object velocities are calculated and used in selecting an appropriate focus value. The calculation of a focus measure takes account of the number of objects in captured frames in order to ensure a consistent calculation of the focus measure.
