    Abstract: Art can be infused with network identifiers at the time of its creation, rather than as a post-process. The identifiers may be encoded as overt elements of the art, and enable the artist to reprogram—as over time—an augmentation of the artwork experience via network-delivered components. These network components can include stimuli present when the artist created the work (e.g., music), commentary by the artist, video and augmented reality features, audience-crowdsourced content (e.g., imagery of, or feedback provided by, other viewers encountering the artwork), etc. The artwork augmentation can vary with the user's context (e.g., location, demographics, interests, history). Physical brushes can be equipped to insert such identifiers in graphic arts; other authoring tools are disclosed as well. The network experience can be delivered via smartphones, projectors, and other devices. A great number of other features and arrangements are also detailed.

    Abstract: The present disclosure relates generally digital watermarking and data hiding techniques. One claim recites a method comprising: obtaining data representing imagery; using one or more configured processors, transforming the data into a multi-channel color space; obtaining information indicating an impact of adding a color channel encoded signal to a color direction of the data; determining a color space direction for encoded signal detection; obtaining weighting factors based on the information indicating an impact of adding a color channel encoded signal; weighting the color channel encoded signal with weighting factors to yield a modified color channel encoded signal; using one or more configured processors, embedding the modified color channel encoded signal in the data representing imagery. Of course, other claims and combinations are provided as well.

    Abstract: The present disclosures relates generally to digital watermarking and data hiding. One claim recites a smartphone comprising: a camera to capture video of a display that is rendering video, in which the video comprises a first watermark signal embedded in a first portion of the data, a second watermark signal embedded in a second portion of the data, and a third watermark signal embedded in a third portion of the data, in which at least two of the first watermark signal, second watermark signal and third watermark signal are inversely related to one another; electronic memory for buffering data representing captured video; one or more electronic processors programmed for: applying a first perspective distortion to the data representing the captured video to yield first perspective distorted video; and analyzing the first perspective distorted video to detect digital watermarking, in which a second perspective distortion is applied to the data representing the captured video to yield second perspective distorted video when the analyzing does not detect digital watermarking, and then performing analyzing the second perspective distorted video to detect digital watermarking. Of course, other claims are provided too.
