Abstract: A user captures an image of a magazine or catalog page with a smartphone. The page is identified by extracting fingerprint or watermark data from the imagery. Other imagery depicting that page is identified, and is displayed to the user on the smartphone screen. Further imagery can also be presented on the screen. This further imagery can include other pages in the publication that are not be consecutive with the captured page, but that are logically linked with it by reference to a data structure. The user may elect to post such imagery to a social network account (e.g., Pinterest) associated with the user. The posting can include an attribution identifying the original publication. A great variety of other features and arrangements are also detailed.

Abstract: Content uploaded to a video distribution service is analyzed to determine if a portion matches part of any reference work. If a match is found, treatment of the uploaded content is determined based on stored rule data, and based on one or more factors. These factors can include, e.g., the length of the matching portion, the part of the reference work from which the matching portion was apparently copied, the confidence of the match, the popularity of the uploaded content (or of the reference work), the geography from which the content was uploaded (or the geography to which it is to be downloaded), etc. Further determinations may be made by human evaluators (including crowd-source approaches). A great variety of other features and arrangements are also detailed.

Abstract: A portable device, such as a cell phone, is used to “forage” media content from a user's environment. For example, it may listen to a television viewed by a traveler in an airport lounge. By reference to digital watermark or fingerprint data extracted from the content, the device can identify the television program, and enable a variety of actions. The device may also identify content that preceded (or follows) the foraged content. Thus, a traveler who views just the end of an exciting sporting event can capture one of the following commercials, identify the preceding program, and download same for later viewing. Relatedly, audio foraging can be used as a source of still imagery. A great variety of other functions and arrangements, e.g., addressing social media, are also detailed.

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 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 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.
