The original image and two differrent external force fields. (a) Cell image captured by the phase-contrast microscope, and the lymphoctye is in the center of the view. The ROI contains the target-lymphoctye, marked as in the rectangular. (b) The traditional external force field based on (5). (c) The proposed external force field based on (7).
