Dynamic Image Analysis Software?

[bergquist at cobra.uni.edu]

I am looking for dynamic image analysis software (should be able to track
moving microscopic images).  This should be color capable and measure a number
of parameters e.g. rate of movement, direction, path length etc.  I would
appreciate any information on programs and sources.

Thanks,
