PillarTracker

The content of this page has not been vetted since shifting away from MediaWiki. If you’d like to help, check out the how to help guide!

PillarTracker enables users to track pillars with drift correction and visualize the trajectories and deflections.

Installation

It can be automatically downloaded and installed via the ImageJ Updater (Help › Update…). Activate the PillarTracker checkbox in Manage update sites. For more details about how to update Fiji in a most convenient way, please refer to our documentation here. However, if user doesn’t want to use the updater for some reason, one can still download it from following link, and then install it manually.

    3. output ROI data for all frames as table.

    4. source code on Github repository.

  • version 1.1.5

    1. draw dragon tails for tracks.

    2. faster create movie.

    3. performance improved for muliti-threading

    4. add mean filter to detect maximas

  • version 1.1.4: beta for internal use

  • version 1.1.3

    1. use pillar reconstruction algorithm to establish exact grid.
