Flotation froth image texture extraction based on LBPV
基于LBPV的浮选泡沫图像纹理特征提取*

In the flotation process, the surface features of the cleaner froth had close connection with the flotation production condition and reflected the mineralization of foam layer(concentrate grade).In order to optimize the flotation operation,this paper proposed a method of LBPV to extract the bubble texture features.The features of bubble image were extracted on the combination of local texture spatial structures and contrast features. LBPV texture features used in the cluster analysis of the flotation operation condition state. Clustering results show that the texture feature are efficient in reflecting the bubble states and can obtain better clustering quality of flotation foam.
