Bubble Sliding and Lift-off Analysis

The image processing code for this package was written in cooperation with Amir Meghdadi. Image processing and data compilation package for analysis of bubble sliding and lift-off events. High speed greyscale videos of bubble nucleation, sliding, and lift-off events are required with either an in-frame scaling device or a known image scale. Individual bubbles are tracked from nucleation to lift-off and various parameters are measured, including sliding velocity, 3D equivalent spherical diameter, base diameter, maximum 3D diameter, lift-off 3D diameter, and (if resolution is high enough in the vicinity of the bubble base) contact angles and the angle of inclination. Parameters are measured in each frame for a particular bubble and are outputted as raw data in a Microsoft Excel file. After the user has analysed all useful bubbles, the data is compiled and summarized in a Microsoft Excel file.
