About Us

Place recognition is a well defined but extremely challenging problem to solve in the general sense; given sensory information about a place such as a photo, can a human, animal, robot or personal navigation aid decide whether that place is the same as any places it has previously visited or learnt, despite the vast range of ways in which the appearance of that place can change.

Current approaches to the problem using GPS, cameras or lasers have one or more significant theoretical, technological or application-based limitations including high cost, sensitivity to changing environmental conditions, lack of generality, training requirements and long recognition latencies.
