A novel
flotation froth image segmentation based on threshold level set method is put
forward in view of the problem of over-segmentation and under-segmentation
which occurs when the existing method segmented the flotation froth images. Firstly,
the proposed method adopts histogram equalization to improve the contrast of
the image, and then chooses the upper threshold and lower threshold from grey
value of histogram of the image equalization, and complete image segmentation
using the level set method. In this paper, the model which integrates edge with
region level set model is utilized, and the speed energy term is introduced to
segment the target. Experimental results show that the proposed method has
better segmentation results and higher segmentation efficiency on the images
with under-segmentation and incorrect segmentation, and it is meaningful for
ore dressing industrial.
