Abstract
This paper introduces an active contour or snake-
based method for tracking cells within a video sequence.
Specifically, we apply our cell tracking techniques to
rolling leukocytes observed in vivo (in living animal) from
video microscopy. The analysis of leukocyte motion
reveals cues about the mechanism of inflammatory
disease. To attack the problem of tracking leukocytes in
vivo, the proposed snake tracker utilizes shape and size
information specific to the leukocytes. The principal
contribution of this work lies in introducing the shape and
size constraint as a geometric primitive in the parametric
snake energy model. The energy functional is then
minimized through the basic principles of the calculus of
variations to obtain the Euler equations used in contour
