Flotation froth working condition identification method based on co-occurrence augmented matrix in dual-tree complex wavelet domain

Abstract

The invention belongs to the technical field of flotation foam industrial and mining identification, and in particular relates to a flotation foam working condition identification method based on a double-tree complex wavelet domain co-occurrence augmentation matrix. The method includes performing dual-tree complex wavelet transform on the image to extract the high and low frequency subgraphs of the image; calculating the gray level co-occurrence augmented matrix of each subgraph based on the dual-tree complex wavelet transform; calculating the eigenvalues ​​of each augmented matrix; Industrial and mining identification model; the eigenvalues ​​of the augmented matrix are used as input feature vectors of the flotation industrial and mining identification model for identification of flotation working conditions. The invention can accurately and quickly realize the working condition recognition of the flotation foam image, avoid the subjectivity and arbitrariness of manual observation, provide the possibility for the optimization control of flotation production, ensure the economic benefits and production efficiency of the enterprise, and ensure the Sustainable development of mineral resources.

Description

technical field [0001] The invention belongs to the technical field of flotation foam industrial and mining identification, and in particular relates to a flotation foam working condition identification method based on a double-tree complex wavelet domain co-occurrence augmentation matrix. Background technique [0002] Metal mineral resources represented by copper are the lifeblood of the economic development of all countries in the world. With the rapid development of the national economy, my country's dependence on copper mines has increased year by year. In recent years, my country's copper consumption has ranked first in the world, accounting for almost half of the world's total copper consumption. However, my country's copper ore resources are scarce, with the characteristics of less rich ore, more lean ore, small scale of deposits, and scattered mining areas. Minerals that have been listed in my country's mineral resources in short supply for many years need to be impo...
