welcome.

please don't use generic subjects like "help" or "i have a question".
most people who write on this list either have a question or try to
answer one. imagine what would happen if all of those would use the
subject "help" or "answer". anyhow this is all explained at [1], which
you probably should read.

[pix_movement]/[pix_blob] is just a standard way to get movement data
from an image. [pix_movement2] is another.
there are some openCV objects out there as well (look for pix_opencv),
which might have more sophisticated tracking algorithms (e.g. based on
shape).

but in all these cases: if the output signal is too noisy, you should
try to reduce the noise by applying a filter: filters are the magic of
tracking.
