hi al, this is my first post and first patch. i'm trying to use a movement, captured by a webcam, as a trigger in order to play sounds. i want to track only the horizontal changes, like from left to right and use that information as a trigger, bang. i know that there is too much information, and i should filter these also. sel object seems useful. i checked the motion detect patch in pd, but i need someone's help and ideas on how i can modify it.

basar.

Where is the motion detection patch??

right, is it:

Manuals > GEM > Video > Movement Detection?

yes, arif, it is. but now, i had a diferent problem, like, i'm getting so different and sometimes useless numbers in different lights. maybe it's because, i have a bad webcam. i changed the threshold of the pix_movement object, but it has to be reconfigured every time i open up the patch.

it seems as though the movement detection patch using the pix_blob object is detecting and outputting the RGB information of the moving image, and not the direction necessarily of the movement.. I'm also searching for this kind of trigger.. the search continues!!
