First Claim
1. A system comprising:
- a 2D camera for capturing imagery of packaged items moving along a path, the packaged items including digital watermarking hidden on their packaging;
one or more processors programmed for;
digital watermark detection of imagery captured by the 2D camera, in which image areas in a captured imagery frame are prioritized for digital watermark detection based on;
i) area brightness, and on ii) area frame location, in which areas around the center of the imagery frame are more highly prioritized relative to areas on the top or bottom of the imagery frame.

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.

5. A system comprising:
-
a 2D camera for capturing imagery of packaged items moving along a path, the packaged items including digital watermarking hidden on their packaging; one or more processors programmed for; digital watermark detection of imagery captured by the 2D camera, in which image areas in a captured imagery frame are prioritized for digital watermark detection based on;
i) area brightness, and on ii) area frame location, in which image area prioritization is based, at least in part, on a training set individualized according to a user'"'"'s characteristics, in which the user'"'"'s characteristics include checkout speed and object orientation.

6. 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; anddetecting 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. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A computer program product being embodied in non-transitory computer readable storage media and comprising processor executable instructions for:
-
obtaining captured imagery representing packaged items, the packaged items including digital watermarking printed on product packaging, the digital watermarking being represented in the captured imagery; 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; anddetecting 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. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
