The recommended Software for post-processing InfraBlue images to generate NDVI is Fiji (Fiji is a version of ImageJ) which contains some additional files that Ned Horning’s Photo Monitoring Plugin.
To see example results of the open source solution for capturing imagery and post-processing to create NDVI click HERE.
To make it easier for everyone, I put together a single ZIP file that has Fiji/ImageJ and the Photo Monitoring Plugin in one. All you need to do is download and extract the contents of the ZIP to your PC. You can launch Fiji/ImageJ immediately, there’s no need for going through an installation process. When Prompted to update click yes, and go through the update process. All set!
ImageJ is a public domain Java image processing program inspired by NIH Image. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.4 or later virtual machine. Downloadable distributions are available for Windows, Mac OS, Mac OS X and Linux.
It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and “raw”. It supports “stacks”, a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations.
It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering.
It does geometric transformations such as scaling, rotation and flips. Image can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. The program supports any number of windows (images) simultaneously, limited only by available memory.
Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available.
ImageJ was designed with an open architecture that provides extensibility via Java plugins. Custom acquisition, analysis and processing plugins can be developed using ImageJ’s built in editor and Java compiler. User-written plugins make it possible to solve almost any image processing or analysis problem.
