This plugin stabilizes jittery image stacks using the Lucas-Kanade algorithm.

Kang Li

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

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.
