This is my collection of scripts for fitting contact angles of tilted drops. There is two methods, polynomial fitting and double sided elliptical fit. A description of the latter method have been submitted to a peer reviewed journal, i will post proper reference when possible.
When downloading the scripts make sure to add all folders and subfolders to the MATLAB path.
I have included two examples:
Example 1: Calculates the contact angle of a single drop image in a *.Tiff format. This example also plots the result of each step in fitting process.
Example 2: Calculates the contact angle for each frame in an *.avi movie. This includes finding the baseline for all images and averaging to get a accurate baseline positioning and includes the possibility to add calibration functions that compensate for any mechanical shift of the drop image during tilting.
