# ImageJ plugins::Thresholding

Here are some plugins for ImageJ.
The plugins were written by Jens Bache-Wiig and myself.
The plugins are free software (in the public domain).
Java 1.5 or later is required.

To install the plugins, copy the .class files to the ImageJ plugin folder.

## Adaptive 3d Threshold 1.22

Thresholds according to a base value and the values beneath a moving mask
of radius N. The formula used is T_xyz = T_base - Average of (local value - T_base) for all neighbours for a pixel with coordinates xyz.
