Abstract：According to the characteristics of the foam bubbles,a new single bubble identification algorithm in liquid image is proposed.This paper gets a clear picture of the foam on the vertical light shooting position.The original foam image is processed by globally thresholding and morphological processing,and then a binary image is obtained.In order to prevent generation loop in contour extraction,this paper proposes a method of removing burrs.After contour extraction,Hough transform is used to identify whether each single communication edge is round like,which by voting for the center and radius,analyzing the voting results and estimating the peak point of the vote from Gaussian distribution function. The method in this paper can be used to identify all single bubbles in the foam image.Finally,analyzing the achieved results,it shows that this single bubble identification method is effect ideal.
