motion detect

goto10's feedback tutorial was the thing that lit my passion for QC. so in a process of messing arround with it, this composition was made. nothing fancy programming wise but i love its visual aesthetics. was my ultimate vj gun for some time now. the motion detection code i found in _1024 particle warfare motion detect example. i realy dont know if its common practice in detecting motion in QC? i didn't find any plugin for that. anyway, this is my first steps so: to be continued..

just for the record, this was what i tried to achieve originaly, found it few days ago: http://www.samkass.com/blog/page4/files/dafa924cd8213188531b4c0359e1b9b5...

Hi all. I like to make something but i don't know how. i like to make "human mapping", with sensors in the musician's bodys, making "moving masks", maybe in quartz composer? with what sensors? its possible? maybe with motion detection? how a can make a movable mask in QC? thanks! marcos

Hi everyone, I'm pretty new at QC and trying to do a tracking composition for my new touch table.

My question is, how can I detect the movement is on or off?

I mean, at the older version of CVTools, I can detect the movement with the structure count of Optical Flow Points node but at the new version of OpenCV, the structure count is always bigger than 0 =/

I'll rewrite my problem becouse my english is poor,

I want to detect to movement. Is it 1 or 0. Then I'll add and reload the optical flow points to catch the move.

Thanks!!
