The characterization section was set to help with characterizing microstructural features from digital images. The examples use a variety of codes to process images, ranging from GUI-based codes such as ImageJ to more hands-on scripts in MATLAB using the Image Processing Toolbox. This particular site contains production and research codes that have been developed both at CAVS and outside for segmenting microstructural features and analyzing the corresponding binary images.

Software for Plotting Data

This section includes links to common data plotting packages. A more comprehensive list of free software is available here.


Full tutorials for the above software are available on their respective sites. A quick start guide for Veusz is available here.

Example Programs for Microstructural Characterization
