Hi list, I read on the TODO of Gem that the motion detection has to be implemented first but I want to know if somebody tried some 'workarounds' to get something like motion detection. I think about using an infrared camera which will input a black/withe signal. Any suggestions?

the TODO should be updated
there should be an example on how to do motiontracking somewhere in the examples-directory (examples/04.video/03)
caveats: the [pix_movement] is an under-optimal movement-detector (only takes 2 frames into account), i have an improved version lingering on one of my machines...
[pix_blob] does not take into account, that some image-sources flip the image, so the Y-axis might be reversed
anyhow, it works quite well (for a blob-detector i mean)

for a project i'm doing, i use a different approach with optical trigger fields that send out a bang, if movement has been detected in a certain area of the incoming image ... it's not tested very well (works for my purpose) and i didn't send it to the gem-list, since it's probably possibly to rewrite it as an abstraction... i attached the source files, maybe it can be of use ... in general i think that image analyse functions in gem should be improved ... either in c++ or in abstractions (whatever is faster)
cheers ... tim
