Marine bubble detection using optical-flow techniques

O. Zielinski, B. Saworski, J. Schulz


Bubble detection and quantification is of high relevance for the observation of gas and fluid seeps within the marine environment. The presented work suggests and successfully investigates the application of an image processing strategy based on the optical flow concept followed by a customised thresholding and a new segmentation approach. Both are applicable for laboratory conditions and in situ video sequences, as shown for a deep-sea methane vent.
