what is the generic motion detector you are using Mathieu? I use pdp...
I use [t a a] with [# -] or with [# abs-] or even [# sq-]. Then I apply
some filters to reduce noise. If I want to have coordinates, I can use
[#moment] to find a single centre.
If I want multiple centres, I can use [#labelling] instead of [#moment].
By generic I mean something that lets you make the decisions yourself
because you put together very simple components that will do the job you
want. In that sense, [t a a] and [# abs-] and [#moment] are simple
things... [#labelling] is a more complex component, but you still have to
provide your own pre-filtering because it can't take direct camera input
in.
