Particle tracking using IDL

John C. Crocker and Eric R. Weeks

The software described on these web pages was developed by John Crocker and David Grier; Eric Weeks has contributed a few supplemental routines, and has designed this web page. There are some good alternatives to our method:

The method and the software

A quick overview:
  1. Read in a single frame, then process it interactively to figure out what settings to use to 'find' the particles you want to study.
  2. Use a macro to repeat everything you did on all the frames you want to analyze.
  3. Link the coordinates found in each frame together to form trajectories.
  4. Analyze the trajectory info as you see fit for your particular experiment. You will have to design this part yourself-- since this is the science part!
