    摘要: Cell phones and other portable devices are equipped with a variety of technologies by which existing functionality can be improved, and new functionality can be provided. Some aspects relate to data driven imaging architectures, in which a cell phone's image sensor is one in a chain of stages that successively act on packetized instructions/data, to capture and later process imagery. Other aspects relate to distribution of processing tasks between the device and remote resources (“the cloud”). Elemental image processing, such as filtering and edge detection—and even some simpler template matching operations—may be performed on the cell phone. Other operations are referred out to remote service providers. The remote service providers can be identified using techniques such as a reverse auction, though which they compete for processing tasks. Other aspects of the disclosed technologies relate to visual search capabilities, and determining appropriate actions responsive to different image inputs. Still others concern metadata generation, processing, and representation. Yet others relate to coping with fixed focus limitations of cell phone cameras, e.g., in reading digital watermark data. Still others concern user interface improvements. A great number of other features and arrangements are also detailed.

    摘要: A user gestures with a wireless mobile phone device to control some aspect of its operation, or the operation of a remote system with which the device communicates. (The gestures may be sensed by tracking movement of a feature across a field of view of a mobile phone device camera.) The resultant operation may additionally depend on other data obtained by the wireless device, e.g., obtained from an electronic or physical object, or sensed from the environment. A variety of other features and arrangements are also detailed.

    摘要: The present invention relates generally to security documents (e.g., banknotes, ID documents, certificates, packaging, etc.). One claim recites a security document including a security pattern provided thereon. The security pattern includes a line structure in which lines width or line spacing is adjusted to convey a predefined, machine-readable pattern in a frequency transform domain. Another claim recites a security document including a security pattern provided thereon. The security pattern is provided in the security document through modifications to a color provided on the security document. The security pattern conveys a predefined, machine-readable pattern in a frequency transform domain. Of course, additional combinations and claims are provided as well.

    摘要: A security document comprising artwork including a security pattern, characterized in that the security pattern has the form of a line structure in which lines width or line spacing is adjusted to carry predefined data. The artwork is generated by the modifying at least one color of at least a part of the artwork to embed the security pattern in the artwork. Methods for detecting the security pattern include use of a frequency domain structure to detect the security pattern despite rotation and scaling of the document, use of signal tiling to improve signal detection, and use of statistical analyses to verify detection of the security pattern.
