Describeed a bubble image segmentation algorithm in floatation. In order to determine bubble size, shape and texture information from the froth images, the images have to be segmented. Because of the large variation of the froth image patterns and quality, it is difficult to existing segmentation algorithm, therefore, we modified and combined different existing image segmentation algorithms to form a new segmentation algorithm for froth images. In the algorithm, we used and modified a thresholding algorithm to automatically detect maximum of bubbles, then perform morphological technique to growing bubble regions. The over-segmentation problem was resolved by a object merging algorithm based bubble shape analysis. In the paper, three froth image segmentation results are demonstrated, which shows that the developed segmentation is reasonable for froth images.
