Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining distributing web applications. One of the methods includes associating at least one user account and at least one developer account with an application execution system, the at least one user account including user data. A web application is transferred from the developer account into a shared area accessible by the at least one user account. A request is received to associate the web application with the user account from the shared area. The web application is associated with the user account, wherein the web application is configured to access the user data of the user account, and wherein access to the user data of the user account is based on authentication associated with the user account. The installed web application is executed using the user data to create user results based on the user data.

Abstract: An image-stack viewer may switch between images in an image stack based on detected interactions with the images that are displayed in the viewer. In particular, a region-of-interest (ROI) in an image may be determined based on an interaction, and image characteristics of the ROI may be evaluated in two or more images in the image stack where the ROI best represents the evaluated characteristics.

Abstract: Digital maps of roads are labeled with features based on information from images of road signs. A segment of a road network with an unlabeled feature is identified, and a street view image of the road segment taken from a known location is generated. An image of a road sign is captured from within the generated street view image and presented in association with the road segment to a user. A label for the unlabeled feature of the road segment is received and stored.

Abstract: The present invention relates to systems and methods for identifying front pages from images representing media. In an embodiment, a system for identifying at least one front page within an image representing media is provided. The system includes a matcher, an aggregator and a reviewer. In another embodiment, a method for identifying at least one front page within an image representing media is provided. The method includes comparing each page to matching criteria to produce a matching confidence score. The method also includes aggregating, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold. The method further includes receiving decision information and identifying front pages from front page candidates based upon the decision information. According to another embodiment, the matching criteria may comprise at least one local, affine invariant feature point.
