A locality-sensitive hash key is generated for the backup data based at least in part on the set of metadata. The Bayesian Network may comprise instantiable nodes, fault nodes, intermediary nodes, a utility node and a decision node. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed alone or in combination, and selected or predetermined regions or segments from uncompressed images may have more pixels removed or combined than other regions. Platinum metal is disposed on the plurality of titania support particles such that a ratio of the average particle surface area to the percentage amount of the platinum metal is between 5 and 50 m2% Pt g.
