I am making a sentry turret with servos and a paintball gun and need to implement real time motion tracing to make the gun shoot anything that moves. how can I code this(any good algorithms, books, tutorials)? I want to make it myself and not use premade solutions.
Lucas-Kanade with Kalman filtering is the bread and butter motion tracking algorithm. However, it's a bit outdated.
We (Success Labs) just published a Lucas-Kanade app for the iPhone. You can read about it here - http://www.success-ware.com/150842/Lucas-Kanade-Detection-for-the-iPhone
There's a link to the AppStore, and source code as well.
HTH, Oded.
