Mineral image recognition is a challenging computer vision problem. Without external tools,
even a human expert cannot distinguish some mineral species accurately. Previous …

Conventional site investigation schemes typically use an empirical sampling strategy, which
involves equal sampling spacing with regular grid patterns. However, this approach assigns …

The implementation methods of finite element analysis (FEA) have remained essentially
unchanged since the inception of FEA in the 1960s. Alterations of any of the input or design …

This paper presents a novel integrated method for interactive characterization of fracture
spacing in rock tunnel sections. The main procedure includes four steps:(1) Automatic …

The conventional discontinuity survey process in the mining industry is known to be a time-
