Speckle TrackerJ is an ImageJ plugin created for recording the position of numerous speckles as they move through time. Speckle TrackerJ combines manual editing and computer assisted techniques to accurately position and track speckles.

Speckle TrackerJ can be used to track diffusing particles, to find the location of speckle appearances and disappearances, and to measure the lifetime of speckles during a movie. Speckle TrackerJ can also be used to track similarly featured objects.
