Embodiment Construction
[0062] The invention proposes a coal-rock classification method based on asymmetric generalized Gaussian model in the wavelet domain on the basis of experimental analysis of images of main coal types and rock types in my country, which can effectively distinguish coal and rocks.
[0063] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0064] Firstly, the basic process of coal rock classification method based on wavelet domain asymmetric generalized Gaussian model is described. refer to figure 1 ,Specific steps are as follows:
[0065] A. In the sample training stage, under the same imaging conditions as lighting environment, camera parameters, etc., a set of coal sample image sets and rock sample image sets are collected by the camera. In order to facilitate the data processing in the subsequent wavelet transform image decomposition process and exclude the influence of non-coal rock backg...
