CHEN Qing, LIU Jinping, GUI Weihua, et al. Spatial structure statistics of froth images based recognition of flotation froth states[J]. CIESC Journal, 2013, (12): 4296-4303.
For the purpose of achieving automatic recognition and objective judgment of the production states of the froth phase
statistical modeling of froth images is introduced in the flotation process monitoring.Firstly
the Weibull distribution is applied to model the statistical distribution of the edge response of the froth images of all-round orientations
which leads to the effectively extraction of the spatial structure features of the froth images.Successively
a Mixture of Gaussian (MoG) model of the statistics of the froth images under each typical froth state is obtained by the statistical learning of the structure features of the froth image samples.Consequently
the froth states can be inferred effectively by the Bayesian inference.The froth state recognition results indicate that the proposed method can monitor the on-line spatial structural changes of the froth images
which achieves more accurate recognition results of the froth states comparing to the other froth image perception based froth state recognition.
