    Abstract: Technology for constructing a symbol template for use by a 1D barcode decoder. One method includes obtaining a first symbol pattern representing a first symbol, the first symbol pattern comprising a plurality of elements, with each element corresponding to a 1D barcode space or bar, in which the first symbol represents one unique 1D bar (b) and space (s) pattern corresponding to a symbol or digit: 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9; obtaining prefix elements, the prefix elements comprising a subset of second symbol elements from a second symbol pattern which precedes the first symbol from within a scanline of image data, the subset being less than a total number of elements within the second symbol elements; extending the first symbol pattern with the prefix elements to yield an overlapping symbol template for use in correlation-based barcode decoding. Other technology provided as well.

    Abstract: A plastic item, such as a beverage bottle, conveys two distinct digital watermarks, encoded using two distinct signaling protocols. A first, printed label watermark conveys a retailing payload, including a Global Trade Item Number (GTIN) used by a point-of-sale scanner in a retail store to identify and price the item when presented for checkout. A second, plastic texture watermark conveys a recycling payload, including data identifying the composition of the plastic. The use of two different signaling protocols assures that a point-of-sale scanner will not spend its limited time and computational resources working to decode the recycling watermark, which lacks the data needed for retail checkout. In some embodiments, a recycling apparatus makes advantageous use of both types of watermarks to identify the plastic composition of the item (e.g., relating GTIN to plastic type using an associated database), thereby increasing the fraction of items that are correctly identified for sorting and recycling. A great number of other features and arrangements are also detailed.

    Abstract: A surface is laser-etched to convey a 2D machine-readable code pattern. Various strategies are detailed to minimize the etching time. Some strategies include modifying the code pattern to reduce a path length traveled by the laser. Some strategies include modifying the code pattern to make it sub-optimal, i.e., making the code pattern a less-faithful approximation of an ideal code pattern. In some embodiments the etched surface is the surface of a plastic container, and the code pattern conveys information indicating the type of plastic of which the container is manufactured. A variety of other features and arrangements are also detailed.

    Abstract: In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. Logos may be identified and used—or ignored—in product identification. A great variety of other features and arrangements are also detailed.

    Abstract: The present disclosure provide technology for encoded signal localization. One claim recites an apparatus comprising: memory for buffering image data, the image data having been captured with a camera and depicting product packaging or a product label; one or more processors programmed for: generating a spatial domain feature set representation of a portion of image data; evaluating the spatial domain feature set with a classifier to predict whether the portion of image data includes a transform domain encoded signal. Of course, other claims, and various combinations and embodiments are disclosed in this patent document.

    Abstract: Digital watermarking is adapted for the variable data printing. A reference signal serves as a proxy for optimizing the embedding a watermark in a host image to be printed. Using the reference signal, embedding parameters are generated, which are a function of constraints such as visual quality and robustness of the machine readable data. Adjustments needed to embed a unique payload in each printed piece are generated using the embedding parameters. These adjustments are stored in a manner that enables them to be efficiently obtained and applied within the RIP or press during operation of the press. Various other methods, system configurations and applications are also detailed.
