Abstract
Abstract The present disclosure relates generally to digital watermarking and grocery/retail store checkout. One claim recites a system comprising: a 2D camera for capturing imagery of packaged items, the packaged items including digital watermarking printed on product packaging; one or more processors programmed for: prioritizing at least some image areas from within at least one captured imagery frame for digital watermark detection based on: i) area brightness, and on ii) area frame location; and detecting digital watermarks from one or more image areas prioritized from the prioritizing image areas, in which the detecting digital watermarks analyzes image areas in order of prioritization. Of course, other features, combinations and claims are also provided.
