Abstract: Systems and methods, including computer software adapted to perform certain operations, can be implemented for providing remotely defined security data to an application extension on a client device. A sequence of instructions and at least one permission indicator associated with the sequence of instructions are received. A first permission indicator is associated with a code extension to a software application adapted to execute at least a portion of the sequence of instructions. The code extension is adapted to perform one or more operations that supplement the operations supported by the software application. An instruction within the sequence of instructions associated with adapted for execution by the code extension and with an activity is identified. The first permission indicator is provided to the code extension. The code extension determines whether performance of the activity is permitted based, at least in part, on the first permission indicator.

Abstract: A load balancing scheme is described for a server cluster. An application identifier is received by the cluster from a client desiring to connect to the application. Each one of the servers in the cluster independently hashes the application identifier into a unique number. This unique number is used to determine a preferred one of the servers for the connection. The servers then each calculate a priority code using the unique number, a load level for each server, and/or a node identifier assigned to the servers in the cluster. If the preferred cluster server is available, it transmits its priority code to the client before the other servers transmit their priority codes. Otherwise, each of the available cluster servers transmits their priority codes to the client. The client selects the cluster server with the most favorable priority for making the connection.

Abstract: Methods and apparatus for constraining solution space in image processing techniques may use the metadata for a set of images to constrain an image processing solution to a smaller solution space. In one embodiment, a process may require N parameters for processing an image. A determination may be made from metadata that multiple images were captured with the same camera/lens and with the same settings. A set of values may be estimated for the N parameters from data in one or more of the images. The process may then be applied to each of images using the set of values. In one embodiment, a value for a parameter of a process may be estimated for an image. If the estimated value deviates substantially from a value for the parameter in the metadata, the metadata value is used in the process instead of the estimated value.

Abstract: Methods and apparatus for robust video stabilization. A video stabilization technique applies a feature tracking technique to an input video sequence to generate feature trajectories. The technique applies a video partitioning technique to segment the input video sequence into factorization windows and transition windows. The technique smoothes the trajectories in each of the windows, in sequence. For factorization windows, a subspace-based optimization technique may be used. For transition windows, a direct track optimization technique that uses a similarity motion model may be used. The technique then determines and applies warping models to the frames in the video sequence. In at least some embodiments, the warping models may include a content-preserving warping model, a homography model, a similarity transform model, and a whole-frame translation model. The warped frames may then be cropped according to a cropping technique.

Abstract: Methods and apparatus for patch-based construction of an object shape from the shading of an image are disclosed. An image is divided into a set of image subregions. For each image subregion, a set of subregion dictionary entries is identified. Each of the set of subregion dictionary entries includes a subregion entry appearance matching an appearance of the respective image subregion and a subregion entry geometry. A set of optimal subregion dictionary entries is identified. Identifying the set of optimal subregion dictionary entries includes minimizing an energy function of the sets of subregion dictionary entries for all image subregions. Each optimal subregion dictionary entry is, for a respective one of the image subregions, a subregion entry associated with a minimum of the energy function. The shape includes a shape construction parameter from a subregion geometry entry of each optimal subregion geometry entry of the set of optimal subregion geometry entries.

Abstract: Systems and methods are presented for simultaneously displaying a plurality of timeline markers within a timeline marker region of an interface for a video application. The timeline marker region may include multiple display tracks within which numerous timeline markers may be positioned for simultaneous display. At a given instant, each timeline marker may appear in a particular one of the multiple display tracks, and the entire collection of timeline markers being simultaneously displayed at that instant may be arranged so that all of the timeline markers appear separately from each other. Pairs of timeline markers which coincide with non-overlapping portions of the timeline may be placed in the same display track, while timeline markers that coincide with overlapping portions of the timeline may be put into separate display tracks, thus guaranteeing that all the timeline markers appear separately from each other.

Accordingly, the source artwork can then be adapted to fit along the destination path using the adjusted ribs.

Abstract: A Web development environment includes a design view mode that provides an expanded view of container constructs within Web page being edited. When operating in a design view of the development environment, the user is provided an option to view all container constructs in an expanded view. The expanded view will temporarily increase the visual attributes of the container constructs allowing the user to more easily access the editing regions within the cells or content locations of the container. Increasing the visual attributes also allows the developer to see the structure of the edited Web page more clearly. When the developer is finished working with the container, he or she may then return to a standard or other view offered by the graphical development environment. The resulting containers will be re-rendered according to the originally-coded size, without the additional space added for viewing in the expanded mode.
