[Ned Horning](http://publiclab.org/profile/nedhorning) (read [original announcement here](http://publiclab.org/notes/nedhorning/5-31-2012/registering-and-processing-photos-acquired-two-cameras)) has released an open source plugin for the cross-platform [ImageJ](http://rsb.info.nih.gov/ij/). It can produce [NDVI composites](/wiki/ndvi) from infrared and visible image pairs as well as [infrablue](/wiki/infragram) images. 

###Features

* align and merge infrared and visible images (including by batch)
* produce NDVI images from image pairs
* produce NDVI images from single "infrablue" images
* select different gradients ("lookup tables" or .lut files) for NDVI display
