I'm new on this forum and I have a lot of questions! First, I will introduce my project. I want to use processing to make a billard assistant. I want to take a video in continue, to analyse it, tag the balls, define the direction of the balls and then project the final on the billard. So we could the direction of the balls in time! 

But the problem is i'm a newbie in programation but I think i have to use OpenCV,GSvideo and artoolkit to do my project. So do I need other tools? And someone can help me ? 

Thank's a lot! And sorry for my bad english, i'm french...
