Bubble Evolution Detector B.E.D. – A Neural Network-Based Approach to Accurately Detect, Classify, and Evaluate Gas Bubbles Captured by A High-Speed Camera on Textured Surfaces

Abstract

Gas bubble emergence is an important indicator of the performance in many processes, for example electrochemical reactions. Using a convolutional neural network (CNN) based on the Darknet/YOLO4-architecture; this software allows the detection and tracking of gas bubbles from high-speed camera videos, even on strongly textured backgrounds. Further, it evaluates growth rates, detachment size and merging of gas bubbles. This allows a good assessment of many important gas formation characteristics, thus helping performance evaluation and identify potential for improvement.
