Features

The major features of this plugin are:

  • Automatically stabilizes/dejitters/aligns grayscale and or image stacks
  • Support for logging alignment coefficients and reapplication to other stacks
  • Support for very large stacks that do not fit in memory
  • Support for macro recorder

Description

The plugin works as follows:

  • It uses the currently shown slice in an image stack as the initial reference, or “template”;
  • It estimates the geometrical transformation needed to best align each of the other slices with the “template”. The estimation and alignment are performed using the Lucas-Kanade algorithm;
  • Once a slice is aligned, the “template” will be updated on the fly using the formula: new_template = a * old_template + (1 - a) * newly_aligned_slice, where “a” is the “template update coefficient” that can be adjusted when the plugin is run.
