Abstract:
1. A method of classifying geological materials using image processing techniques, the method comprising: correcting the color of an input image of a geological material to be classified; analyzing a color space of the color-corrected image and obtaining a color component value and a change of the color component value; analyzing the granularity of the geological material represented by the color-corrected image; analyzing the texture of the geological material represented by the color-corrected image; and performing a predetermined learning based on the results of the color analysis, the granularity analysis and the texture analysis, and classifying the geological material, wherein the analysis of the granulometry of the geological material comprises: extracting a brightness image from the color-corrected image; repeating an opening operation used in mathematical morphology on the brightness image while varying a window which is a structuring element and obtaining a granularity cumulative curve and a granularity density curve; and obtaining the granularity of the geological material based on figures on the granularity cumulative curve and the granularity density curve.
