Paper Abstract

In this paper, the image processing and parameters measurement method of rising bubbles has been studied. The original bubble image captured is pre-processed with image gray processing, difference image and median filter. According to the characteristic of bubble images, the improved Otsu method with dynamic threshold compression is used 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. After the aforementioned image processing algorithms and processes, the shape feature parameters of bubbles such as perimeter, area, circularity, and mass center coordinate can be extracted effectively as well as the measurement of bubble velocity.The experimental results show that the method is easy, robust and effective, and the parameters of bubbles can be measured precisely.
