Parameter measurement of micro-bubbles in water based on digital image processing

JIAO Bin-liang1,2,QIN Xiao-hui1(1.College of Information Science and Engineering,Yanshan University,Qinhuangdao 066004,China; 2.The Key Laboratory for Special Fiber and Fiber Sensor of Hebei Province,Qinhuangdao 066004,China)  
The bubble images taken from laboratory condition became clear bubble images after a series of image processing operations.The scanning method is used to measure the diameters of the bubbles.Particle Track Velocimetry(PTV)is used to measure the velocity of the sparse bubbles.Particle Image Velocimetry(PIV)is used to measure the velocity of the high density of bubbles.All the above methods have got the corresponding measurement results.That provides a reference for the measurement of micro-bubbles in industry.
