    摘要: The present disclosure relates to signal processing. One claim recites a method comprising: receiving an imagery or audio file; utilizing a configured multi-purpose electronic processor, identifying perceptual features in the imagery or audio file; and based on the perceptual features or data representing the perceptual features automatically creating metadata for the imagery or audio file. The act of automatically creating metadata utilizes at least some data obtained from a process in a portable computing device, the process comprises communication with a device that is separate from an apparatus that is performing the method. Of course, other claims and are provided too.

    摘要: A method of segmenting a media signal for parallel watermarking operations sub-divides the media signal into segments, distributes the segments to parallel processors, and performs parallel digital watermark operations on the segments in the parallel processors. These parallel processors may comprise separate threads of execution on a processing unit, or several execution threads distributed to several processing units. In one enhancement, the method prioritizes the segments for watermarking operations. This enables finite processing resources to be allocated to segments in order of their priority. Further, processing resources are devoted to segments where the digital watermark is more likely to be imperceptible and/or readable. A system for distributed watermark embedding operations includes a watermark signal generator, a perceptual analyzer and a watermark applicator. The system supports operation-level parallelism in the concurrent operation of watermark embedder modules, and data parallelism in the concurrent operation of these modules on segments of a media signal to be embedded with an imperceptible digital watermark.

    摘要: This disclosure describes methods for using embedded auxiliary signals in documents for copy detection. In one implementation we embed an auxiliary signal with a first color that is out of gamut with process color inks or with a particular range of printers. A process color approximation of the first color yields a relatively different contrast when, e.g., viewed with an interference filter. A copy is determined based on the relative presence or absence of the auxiliary signal. In another implementation, we provide a first auxiliary signal with a first color and a second auxiliary signal with a second color. A filter is matched according to the spectral response of the first color. The second color preferably includes a spectral response that is inversely related to the matched filter. The first signal is then detectable in a process color copy, but less so in the original. However, the second signal is detectable in the original, but less so in the copy. In still other implementations we compare relative contrast of a signal to determine an original from a copy.

    摘要: Art is 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—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.

    摘要: The present invention relates generally to documents such as printed documents. One claim recites a printed document including a machine-readable signal. The document includes: a first set of print structures conveyed with first ink; and a second set of print structures convey with optical variable ink. The second set of print structure are provided to cooperate with the first set of print structures so that at a first observation angle the first set of print structures and the second set of print structures appear to provide a first visibly perceptible feature. At a second observation angle, the second set of print structures appear less observable so that the first set of print structures and the second set of print structures provide a second visibly perceptible feature. Of course, other claims and combinations are provided as well.

    摘要: The present invention provides steganographic and digital watermarking methods and apparatus. In a first implementation, we provide methods and apparatus for steganographically conveying data in a facial image by subtly altering facial features relative to statistical norms. In a second implementation, we convey data through different patterns of a diffraction grating. In a third implementation, we convey a digital watermark orientation component by projecting the orientation component onto an object to be captured. In the case of blue-screen technology, we incorporate an orientation component into a blue-screen itself. This provides great convenience for digital animators when overlay graphics and animation. In a forth implementation, we provide an identification document including an electronic memory chip. The chip includes an image of a bearer of the identification document. The image is digitally watermarked to include information (e.g., a chip serial number or document number) that is carried by the identification document. Thus, the electronic memory chip is tied to the document.

    摘要: The present disclosures relates generally to digital watermarking and data hiding. One claim recites a method comprising: obtaining data representing video; using one or more programmed electronic processors, embedding a first watermark signal in a first portion of the data, the first watermark signal comprising a first signal polarity; using one or more electronic processors, embedding a second watermark signal in a second portion of the data, the second watermark signal comprising a second signal polarity that is inversely related to the first signal polarity; rendering the watermarked video in real time, in which due to temporal averaging of the first watermark signal and second watermark signal over time, the first watermark signal and the second watermark signal are hidden from a human observer of the video. Of course, other claims are provided too.
