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： 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.
摘要翻译：对并行水印操作的媒体信号进行分割的方法将媒体信号分割成段，将段分配到并行处理器，并对并行处理器中的段执行并行数字水印操作。这些并行处理器可以包括处理单元上的单独的执行线程，或者分配给多个处理单元的几个执行线程。在一个增强中，该方法优先考虑用于水印操作的段。这使得有限的处理资源按照它们的优先级顺序被分配给段。此外，处理资源专用于数字水印更可能不可察觉和/或可读的段。用于分布式水印嵌入操作的系统包括水印信号发生器，感知分析器和水印施加器。该系统支持水印嵌入器模块并行操作中的操作级并行性，并且在这些模块的并行操作中将数据并行化到要嵌入不可察觉的数字水印的媒体信号的片段上。

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.
摘要翻译：本公开描述了在用于复制检测的文档中使用嵌入式辅助信号的方法。在一个实现中，我们使用具有处理颜色墨水或特定范围的打印机的第一种颜色嵌入不同色域的辅助信号。当例如用干涉滤光片观察时，第一种颜色的处理颜色近似产生相对不同的对比度。基于辅助信号的相对存在或不存在来确定副本。在另一实现中，我们提供具有第一颜色的第一辅助信号和具有第二颜色的第二辅助信号。滤光片根据第一种颜色的光谱响应进行匹配。第二种颜色优选地包括与匹配滤波器相反的光谱响应。然后第一个信号可以在过程颜色拷贝中检测到，但在原始信号中不太可能。然而，第二个信号在原件中是可检测的，但在副本中较少。在其他实施方式中，我们比较信号的相对对比度以从副本确定原件。

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： Arrangements involving portable devices (e.g., smartphones and tablet computers) are disclosed. One arrangement enables a content creator to select software with which that creator's content should be rendered—assuring continuity between artistic intention and delivery. Another utilizes a device camera to identify nearby subjects, and take actions based thereon. Others rely on near field chip (RFID) identification of objects, or on identification of audio streams (e.g., music, voice). Some technologies concern improvements to the user interfaces associated with such devices. Others involve use of these devices in connection with shopping, text entry, sign language interpretation, and vision-based discovery. Still other improvements are architectural in nature, e.g., relating to evidence-based state machines, and blackboard systems. Yet other technologies concern use of linked data in portable devices—some of which exploit GPU capabilities. Still other technologies concern computational photography. A great variety of other features and arrangements are also detailed.

摘要： This patent document relates generally to steganography and digital watermarking. One claim recites, in a watermark detector, a method of decoding auxiliary information encoded encoding in an image or video. The method includes: receiving data representing the image or video, wherein the data comprises first data corresponding to a first color channel, second data corresponding to a second color channel and third data corresponding to a third color channel; 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 anticipated embedding direction; and ii) anticipated image or video distortion introduced to the first data, second data or third data through scanning 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.
