Measure of microscopy mineral image clarity constructed using the sequentially combined toggle and top‐hat based contrast operator

Abstract

Correctly and effectively quantifying the clarity of microscopy mineral image is important and useful to produce clear image for mineral analysis. To well quantify the clarity of mineral image, an effective measure constructed using the sequentially combined toggle and top-hat based contrast operator is proposed in this article. First, the sequentially combined toggle and top-hat based contrast operator is used to extract the effective features which represent the clarity of mineral image. Second, the multiscale clarity features corresponding to each scale are extracted. Finally, after combining the multiscale clarity features in one feature image, the mean value of the feature image is constructed as the measure of mineral image clarity. Because the sequentially combined toggle and top-hat based contrast operator could effectively extract the clarity features, the clarity features are directly used as the measure of image clarity. Therefore, the proposed measure is effective and reasonable. The experimental results on different types of microscopy mineral images verified the effective performance of the proposed measure.

Microscopy mineral image enhancement through center operator construction

“…However, because of the inefficient operation of the microscopy or difficulty in producing reasonable mineral samples, some produced microscopy mineral images are unclear [2,3,6,7]. Enhancing these images to produce clear mineral details and spatial information is valuable for mineral analysis [4,5,8]. And image enhancement is a useful method [9][10][11][12][13][14][15][16][17][18].…”
