SwisTrack is a tool for tracking robots, humans, animals and objects using a camera or a recorded video as input source. It uses Intel's OpenCV library for fast image processing and contains interfaces for USB, FireWire and GigE cameras, as well as AVI files.The architecture of SwisTrack is flexible to allow the user to track (marked and marker-less) objects in many situations. So-called components are stuck together within the component pipeline (like Lego bricks) and configured.
