Binary Segmentation Algorithm Selection and Hyperparameters Optimization of Blasted Rock Image
Journal of Engineering, Volume 2026, Issue 1, 2026.Due to the severe noise and complex texture of blasted rock, selecting an appropriate binary segmentation algorithm is essential. This study evaluates nine common local thresholding methods for segmenting blasted rock images, with a focus on hyperparameter optimization of the highly adaptable Phansalkar algorithm.

Evolution and mechanism of rockburst induced by structural plane based on GDEM
Meitan xuebao, 2023 In the process of deep underground rock excavation, the surrounding rock of cave wall often causes some rockburst geological disasters due to the weakening of structural plane. In order to reveal the influence of the existence of structural plane on the rockburst induction mechanism, in this paper, adopting the finite element and discrete element ...
