computer visionkalman filter plugin (Composition by dust)
kalman vector filter. a kalman filter is used heavily in computer vision as it is an included filter. you can use it to predict things like musical notes or something its arbitrary the data. normally it is used to smooth out values that have some sort of noise in them. http://kalman.sourceforge.net/ openCV shape recognition help Hi there, I’m an industrial design student (definitely not a programmer) looking at making a learning tool -and I really need some help! I want a user to be able to construct a basic 2d shape out of popsicle sticks and an overhead camera to recognize the shape and play an audio track which correlates.... ie, the user makes a triangle out of sticks and the computer plays “well done, it’s a triangle”. So a basic requirement, but quite difficult to pull off. I think CV is the best solution, as I want the kids to be able to construct basic shapes by themselves (and not on a grid), and the linear construction elements (popsicle sticks) should be disposable - so sensors attached to them aren’t really appropriate) That said, IR leds would be ok I’ve been considering openCV with a database of comparative images of shapes (haar learning) but it’s beyond my knowledge. I do however have some experience with quartz composer, so that would be my first choice. Any suggestions for setting up what is basically computer vision pattern recognition? cheers, I really appreciate your time, Jeremy
