A Real Time Coal Content/Ore Grade (C2OG) Sensor, Technical Report: April - June 2004

Description: This twelfth quarterly technical report discusses work on classification algorithms and an improved lighting system. Measurements on core in the Stillwater Mine core room showed that false positive sulfide classifications occurred at breaks in the core and there were also problems with camera saturation due to glints from crystal facets within the core. To reduce false positives due to noisy data, a wavelet transform smoothing program was explored. Results indicate classifications improve only … more

A Real-Time Coal Content/Ore Grade (C2OG) Sensor, Technical Report: April - June 2003

Description: This eighth quarterly technical report discusses the progress made on a machine vision technique for determining coal content and preparations for Year-3 system deployment. Classification maps for coal have been generated and shown to two coal-mining executives. An application for licensing high-speed hyperspectral data analysis software from the Naval Research Laboratory (NRL) has been made. Both Western Energy and Stillwater Mining Company have offered platforms for Year-3 deployment. Barrett… more
