Gas Bubble Shape Measurement and Analysis

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8753)

Abstract

This work focuses on the precise quantification of bubble streams from underwater gas seeps. The performance of the snake based method and of ellipse fitting with the CMA-ES non-linear optimization algorithm is evaluated. A novel improved snake based method is presented and the optimal choice of snake parameters is studied. A Kalman filter is used for bubble tracking. The deviation between the measured flux and a calibrated flux meter is 4 % for small and 9 % for larger bubbles. This work will allow a better data gathering on marine gas seeps for future climatology and marine research.
