Hello,

I searched the list archives briefly, but didn't find this topic
specifically. It's entirely possible that I simply didn't know what to
look for.

I have access to GOES 12 satellite data (i.e. cloud data) as either
raw data, TIFF files - frame by frame - or High definition QuickTime
movie.

I'd like to use some image-processing techniques to identify pixels
that you and I would group togther as a clouds, and track their motion
from one frame to the next.

Analyze particles seems to work well to identify clouds in a given
frame. Are there any commands / plug-ins / algorithms to track their
motion/change across frames (i.e. can I get a dataset that tells me
that a given particle in the current frame is the same particle as one
found in the previous frame, although its size, shape, and/or position
have changed slightly)?

Thanks,
Brian
