    Abstract: This patent document relates generally to steganography and digital watermarking. One claim recites a method comprising: receiving data representing image or video, in which the data comprises first data corresponding to first color data, second data corresponding to second color data and third data corresponding to third color data, the image or video to host auxiliary information; weighting the first data, the second data and the third data according to at least the following two factors: i) a color direction biased toward an expected embedding direction; and ii) expected image or video distortion introduced to the first data, second data or third data through image capture or signal processing; and determining from weighted first data, weighted second data and weighted third data, changes in an image or video attribute, in which the auxiliary information is conveyed through the changes to sample values representing the image or video. Of course, other claims are provided too.

    Abstract: The disclosure describes a method of connecting multimedia content to a network resource. This method operates in a computer network environment. Operating in a network connected device, the method extracts an identifier from a media signal, such as from a digital watermark, perceptual hash, or other machine extracted signal identifier. It then sends the identifier to a network along with context information indicating device type information. From the network, the method receives related data associated with the media signal via the identifier. The related data is adapted to the network connected device based on the device type information. This device type information may include a display type, so that the related date may be formatted for rendering on the display type of the device. This device type information may also include a connection speed so that the related data may be optimized for the connection speed of the device.

    Abstract: Items are identified in a waste stream for purposes of recycling, using deterministic and/or probabilistic techniques. Imagery of the waste stream from multiple viewpoints permit creation of a 3D depth draped image representation, from which one or more 2D planes can be synthesized. Phase-coherent patches of recoverable encoded data can be identified from among soiled and crumpled object surfaces, and used in combination to recover object identification information. Recognition of certain items can trigger further image processing that is specific to such items. (Detection of a catsup bottle, for example, can trigger image analysis to discern the presence of catsup residue.) Information about recognized objects can be provided to external data customers, e.g., to track grey market diversion of particular products into unlicensed territories. These and other features and advantages, which can be used alone or in combination, are detailed herein.

    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: A waste stream is analyzed and sorted to segregate different items for recycling. Certain features of the technology improve the accuracy with which waste stream items are diverted to collection repositories. Other features concern adaptation of neural networks in accordance with context information sensed from the waste. Still other features serve to automate and simplify maintenance of machine vision systems used in waste sorting. Yet other aspects of the technology concern marking 2D machine readable code data on items having complex surfaces (e.g., food containers with integral ribbing for structural strength or juice pooling), to mitigate issues that such surfaces can introduce in code reading. Still other aspects of the technology concern prioritizing certain blocks of conveyor belt imagery for analysis. Yet other aspects of the technology concern joint use of near infrared spectroscopy, artificial intelligence, digital watermarking, and/or other techniques, for waste sorting. A variety of further features and arrangements are also detailed.
