Abstract: A method for image capture includes identifying a bright spot in an image. A neural network is used to recover details in bright spot area through a trained de-noising process.

Abstract: A method of quantifying at least one property of interest of an oil sands ore sample is provided using a laser-induced breakdown spectroscopy (LIBS) method. The LIBS method may be applied to oil sands ore being conveyed prior to a slurry process to measure oil sand composition and provide information which may predict extraction characteristics. The LIBS method may be applied to oil sands core samples in a laboratory setting to reduce the cost and analysis time associated with conventional laboratory measurement techniques.

Abstract: A system for characterizing a slurry in a slurry process includes a flow tube, a camera, and a computer. The system is suitable for use with an oil sands extraction slurry processed or treated by an oil sands extraction slurry process. The slurry is diverted from the slurry process into the flow tube. The camera images the slurry as it flows through a transparent portion of the flow tube to produce a digital image of the slurry. The computer analyzes the digital image to determine a slurry characteristic. Based on the determined slurry characteristic, the computer may predict a performance metric of the slurry process and adjust an operating parameter of the slurry process to optimize the slurry process towards a target performance metric. Multiple systems may be used to continuously monitor slurry characteristics at upstream and downstream steps of the slurry process, and determine correlations between those characteristics.
