Abstract: A live wallpaper for a computing device is disclosed. The live wallpaper displays imagery from various image sources (e.g. Picasaweb, Panoramio, Google+, Facebook, Twitter) and displays new imagery upon the occurrence of various trigger conditions, such as upon user interaction with the live wallpaper or upon the passage of a period of time. In a particular implementation, the live wallpaper can be configured to display geolocated photographs associated with a geographic area input into the computing device. For instance, geolocated photographs associated with a user's current location can be displayed and can change automatically as the user's locality changes. The live wallpaper can be configured to display imagery that has not previously been displayed as the wallpaper on the computing device to present new and unseen images and different backgrounds for the computing device.

Abstract: A computer implemented system and method are disclosed for segmenting aerial and satellite imagery according to pre-defined regions contained in the images such as city blocks. An example system comprises a feature mask generation module, a partition generation module, one or more color map generation modules, a color map reassignment module, and a bounding box generation module. The system and method take aerial image data and vector map data as input and generate a composite color map for a geographic region of interest, wherein the color map comprises a plurality of pre-defined regions in which each pre-defined region can be defined by enclosing road segments. The disclosed system and method provide a convenient and logical way of segmenting large data sets of aerial imagery for use in other applications such as the construction of computer models of surface features of the Earth.

Abstract: A method for processing graphics data packets comprises allocating an entity for the graphics data packet of vertices, triangles, and/or pixels in one or more execution blocks that receives an assignment from a global spreader to process the graphics data packets. A pointer, which points to the allocated entity, communicates a pointer to a data mover, and the data mover loads some graphics data packets into a memory. A number of processing stages may follow such that one or more floating point or integer instructions is executed on the graphics data packets, as controlled by a thread controller. Upon completion of calculations on the graphics data packets, the allocated entity may be deleted and the graphics data packets may be communicated to another execution block or as directed by the global spreader.
