A computer vision approach to calculate diameter, volume, velocity and flow rate of bubble leaks in offshore wells

This paper presents an approach for detection and quantification, with low latency, of the flow of leakage bubbles, in sub-surfaces, making use of video recorded by remote underwater vehicle using only image analysis and under the premise of no overlapping bubbles. Implementation details are presented allowing its trial and reproduction. Results are confronted with videos acquired in a laboratory under controlled conditions and in real operational situation from literature, showing great efficiency in terms of processing time and all other important aspects for pipeline inspections, considering environment and safety in the oil industry.
