Abstract: Disclosed are technologies are useful in enabling a smart phone to respond to a user's environment, e.g., so it can serve as an intuitive hearing and seeing device. Some of the detailed arrangements involve using radio base station SDR equipment (e.g., at a cell tower) to perform image recognition operations for phones; forecasting service needs from remote processors delegating a remote execution task to a service provider chosen in a competitive process; using nearby processors, e.g., in an automobile, another phone, or set-top box, for remote execution tasks; phones with separable camera and/or illumination components; phone camera illumination using different colors of light; using search tree methods with image frames captured at different focuses; using a phone's microprojector to aid in object identification; correcting lens aberrations by texture mapping captured imagery onto a corrective polygon surface using a phone GPU; etc. A great variety of other features are also detailed.

Abstract: Mobile 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 visual search capabilities, and determining appropriate actions responsive to different image inputs. Others relate to processing of image data. Still others concern metadata generation, processing, and representation. Yet others concern user interface improvements. Other aspects relate to imaging architectures, in which a mobile phone's image sensor is one in a chain of stages that successively act on packetized instructions/data, to capture and later process imagery. Still other aspects relate to distribution of processing tasks between the mobile device and remote resources (“the cloud”). Elemental image processing (e.g., simple filtering and edge detection) can be performed on the mobile phone, while other operations can be referred out to remote service providers.

Abstract: A system manages display and retrieval of image content on a network by identifying the image and linking the image to related information, such as licensing information or usage rights. The system manages the display of image content stored within a network by associating thumbnail images that link to versions of the image content stored on a network. One example is a thumbnail that acts as a bookmark linking to image signal content stored on a distributed network of computers, such as links to web pages accessible on the internet. Corresponding methods are also provided.

Abstract: 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.

Abstract: A kiosk for reading a digital watermark from a physical object (e.g., a printed document) can be used in various contexts, including retail systems designed to provide customers with product information; corporate greeting systems used to register or direct a visitor; computer terminals in public environments—such as cyber cafés—which can be used to access the Internet; and registration terminals at service centers, such as a copy center, that are used to request services or provide information. An illustrative kiosk may include a housing with a computer concealed inside. On the outside of the kiosk is an illuminated stage on which the user can place the object to be read. An image sensor (e.g., a webcam) captures an image of the object placed on the stage, and the computer processes the image to decode the watermark payload. The computer than responds to the user (e.g., via a display screen or audio transducer) with responsive information.

Abstract: A variety of systems responsive to watermarked documents are detailed. In one, watermarking is employed to facilitate secure online transactions. In another, a system for exchanging data is provided. One system includes a user terminal and a central site. The user terminal includes a watermark reader, and a capture device to capture an image of a watermarked document. The central site includes a database of image hashes. The user terminal communicates with the central site. The watermark reader reads a watermark and computes a hash of a captured image, and passes the hash to the central site for comparison with the database of image hashes.

Abstract: The present invention relates to linking on-line data to printed documents, such as business cards, envelopes, stickers, stationary, letterhead, résumés, etc. In one embodiment, a card-user registers with an on-line database and receives a gallery item including a steganographically-embedded unique identifier. The gallery item, such as a graphical background, text, shading, graphic, etc., is integrated and then printed with a document. The printed document can then be presented an optical-scanner, which outputs data. The output data is decoded to identify the unique identifier. The unique identifier is then used to index into the on-line database to retrieve information related to the proprietor of the document. In one embodiment, the on-line database includes features such as providing an immediate contact number, translation and/or pronunciation ability, and storage of audio/video files.
