Study of Edge Detection Methods on Flotation Froth Image

According to the timely gathered flotation froth image in industrial spot, the way of finding froth edge and the watershed Flooding method were put forward for segmenting image. The algorithm procedure of finding froth edge was expounded, and the definition of watershed and pseudo C algorithm of Flooding method was given. At last, experimental results of two methods are compared and analyzed. The result shows that the two methods are feasible to industrial application.
