OpenBubble

Co-developed OpenBubble a toolbox to detect, track, analyze bubbles in a moving fluid.

The Python-based GUI predicts bubble behaviors by leveraging imaginary trajectory generation, multi-bubble coordination, hybrid position, force control, and path and behavioral planning optimization.

It also marks bubble boundaries of video files of bubbly moving fluid while ignoring shadows, reflection, poor illumination, etc. It counts and tracks bubbles considering some merge, and produces a histogram, measures the bubble dimension, and performs velocimetry analysis. It is capable of filtering bubble (object) detections based on 14 criteria including convexity, area, and inertia ratio of the bubbles.
