Ascertainable clustering number is one of the vital problems of spectral clustering. To solve this problem, a spectral clustering algorithm automatically determining the clustering number is proposed. By mapping the sample point of the data set into feature space, the orthogonal positional relationship of sample points between different clusters in the(More)
The variable of froth velocity is an effective flotation optimal control parameter in the machine vision based flotation monitoring and control, which closely related to the flotation performance indices. However, the bubble velocity extracted based on digital image processing is often difficult to accurately extract, due to the inevitable rotation, scaling(More)
