    Abstract: A system and method of object detection are disclosed. In a particular implementation, a method of processing an image includes receiving, at a processor, image data associated with an image of a scene. The scene includes a road region. The method further includes detecting the road region based on the image data and determining a subset of the image data. The subset excludes at least a portion of the image data corresponding to the road region. The method further includes performing an object detection operation on the subset of the image data to detect an object. The object detection operation performed on the subset of the image data is exclusive of the at least a portion of the image data corresponding to the road region.

    Abstract: In a particular embodiment, a method includes evaluating, at a mobile device, a first area of pixels to generate a first result. The method further includes evaluating, at the mobile device, a second area of pixels to generate a second result. Based on comparing a threshold with a difference between the first result and the second result, a determination is made that the second area of pixels corresponds to a background portion of a scene or a foreground portion of the scene.

    Abstract: The disclosed technology relates to image-capturing methods. In one aspect, a method includes receiving an image frame comprising a plurality of pixels and subtracting foreground pixels from the image frame to obtain background pixels. The method additionally includes determining an exposure condition for a next image frame based on at least a subset of the background pixels. The method further includes adjusting the foreground pixels such that a difference between a background luma value and a foreground luma value of the next image frame is within a predetermined range. Aspects are also directed to apparatuses configured for the methods.

    Abstract: A method and system for generating and tracking dynamic advertisements within a program, such as a video game, running on a portable computing device (PCD) are described. The method and system include receiving a call from the program for a texture and reviewing an identifier associated with the texture. A graphics driver determines if the identifier associated with the texture matches an identifier in a texture database. The graphics driver then selects a dynamic advertisement from a texture database if the identifier associated with the texture matches the identifier in the texture database. The graphics driver issues commands to the graphics processor so that dynamic advertisement is presented on a screen display. The graphics driver then determines if a video object produced by the program blocks a portion of the dynamic advertisement present on the screen display.
