Tracker is an image and video analysis package built on the Open Source Physics Java framework. Features include object tracking with position, velocity and acceleration overlays and graphs, special effect filters, multiple reference frames, calibration points and line profiles for analysis of spectra and interference patterns. It is designed to be used in introductory college physics labs and lectures.
Information about Tracker is available on the Tracker website.
Tracker technology has been integrated into the core OSP library to allow OSP programs to easily capture a computer simulation's output as an animated GIF or as a QuickTime movie. (Apple QuickTime must be installed to create QuickTime movies.) Chapter 13: Video of the Open Source Physics Guide describes the OSP video API for programmers and Chapter 16: Tracker of the Open Source Physics Guide describes the Tracker video analysis program.
