Estimating the bubble size distribution characteristics in foam images

Wu Yan-peng, Peng Xiao-qi, Song Yan-po

This paper proposes a statistic model for estimating the bubble size distribution in foamimages based on uniformscanning and edge analysis. It also presents the algorithmfor calculating the bubble size distribution of circular bubbles aswell as oval bubbles, completewith aweighted statistical algorithmof bubble size distribution under the condition ofmulti-directioned uniform scanning. The simulation results indicate that the widths of the bubbleÂ’s section lines and bubble sizes are identically distributed, and the estimated number of bubbles in the foam image is similar to the actual value.
