Ore-Waste Discrimination Using Supervised and Unsupervised Classification of Hyperspectral Images

Autor: Mehdi Abdolmaleki, Mariano Consens, Kamran Esmaeili

Publikováno v: Remote Sensing, Vol 14, Iss 24, p 6386 (2022)

Ore and waste discrimination is essential for optimizing exploitation and minimizing ore dilution in a mining operation. The conventional ore/waste discrimination approach relies on the interpretation of ore control by geologists, which is subjective
