ContactAngle is a simple and easy-to-use program to extract contact angles from videos of liquid droplets on a surface.
The program is free and open source under a BSD license and will work on various flavors of BSD, Linux, and Windows. It uses the OpenCV computer vision library for image processing and the wxWidgets toolkit for the user interface.
It was originally created to optimize layer structures for digital microfluidic (DMF) devices for work done at the EMSG research group at the University of Edinburgh, Scotland, UK.
