Abstract: Disclosed are methods, systems, and articles of manufactures for addressing popular topics in a social sphere. The method or the system continuously monitors conversations in online forum(s), identifies trend(s) of interest, identifies one or more content items that match the trend(s), and delivers the one or more content items to appropriate forum(s). The method or the system may aggregates conversations in a target forum to identify a trend and automatically responds to the trend by identifying and delivering matching existing content items to a target forum. The method or the system may further catalog a newly created content item upon creation and may identify a trend by employing some third-party products or services, by executing one or more Internet bots to monitor the online conversions, or by using trending application(s) offered by forums or social network websites.

Abstract: An electronic device that determines a geometric scale of an object using two or more images of the object is described. During operation, the electronic device calculates the size of the object along a direction using multiple images of the object that were taken from different perspectives (such as different locations and/or orientations in an environment) along with associated imaging-device characteristics. For example, the size of the object may be calculated using the images, the associated focal lengths of a digital camera that acquired the images, and the law of cosines. Using the scale of the object, an image of the object may be appropriately scaled so that it can be combined with another image.
