Extraction of bubble shape and motion feature parameters in the gas-liquid two-phase flow

XUE Ting,MENG Xin-dong,ZHANG Tao(Tianjin Key Laboratory of Process Measurement and Control,College of Electrical Engineering and Automation,Tianjin University,Tianjin 300072,China)  
Extraction of shape and motion feature parameters of rising bubbles has been studied.The original bubble image is captured and pre-processed with image gray processing,difference image and median filter.According to the characteristics of bubble images,the improved Otsu method with dynamic threshold compression is presented for image binarization,and the scan line seed fill algorithm is combined with morphological image processing to implement holes filling.Simultaneously,automatic identification technique of bubble feature regions is proposed based on the edge area attribute.The experimental results show that the method has merits of easy realization,strong robustness and effectivity for separating bubbles from the background;the shape feature parameters of bubbles such as perimeter,area,circularity,and mass center coordinate can be extracted effectively,and the bubble motion velocity is also achieved.
