Abstract: Disclosed herein are systems and methods for persona identification using combined probability maps. An embodiment takes the form of a method that includes obtaining at least one frame of pixel data; processing the at least one frame of pixel data to generate a hair-identification probability map; and generating a persona image by extracting pixels from the at least one frame of pixel data based at least in part on the generated hair-identification probability map.

Abstract: Disclosed herein are methods and systems for generating a user-hair-color model. One embodiment takes the form of a process that includes obtaining video data depicting a head of a user. The process also includes determining a set of line segments of pixels of the video data, wherein each line segment in the determined set of line segments intersects an upper contour of the depicted head of the user. The process also includes grouping at least some of the pixels of at least one of the line segments in the determined set of line segments into three sets of pixels based at least in part on respective color data of the pixels. The three sets of pixels include a skin-pixel set, a hair-pixel set, and a background-pixel set. The process also includes updating a user hair-color model based at least in part on the skin-pixel set.

Abstract: Disclosed herein are systems and methods for extracting person image data comprising: obtaining at least one frame of pixel data and corresponding image depth data; processing the at least one frame of pixel data and the image depth data with a plurality of persona identification modules to generate a corresponding plurality of persona probability maps; combining the plurality of persona probability maps to obtain an aggregate persona probability map; and generating a persona image by extracting pixels from the at least one frame of pixel data based on the aggregate persona probability map.

Abstract: Disclosed herein are methods and systems for presenting personas according to a common cross-client configuration. An embodiment takes the form of a method that includes extracting a persona from video frames being received from a video camera. The method also includes transmitting an outbound stream of persona data that includes the extracted persona. The method also includes receiving at least one inbound stream of persona data, where the at least one inbound stream of persona data includes one or more other personas. The method also includes presenting a full persona set of the extracted persona and the one or more other personas on a user interface according to a common cross-client persona configuration. The method also includes presenting one or more shared-content channels on the user interface according to a common cross-client shared-content-channel configuration.

Abstract: Embodiments of the present invention provide a circuit for a MIDI controller that may be used with keyboard and drawbar interfaces provided by a variety of models of drawbar-type electric organs. Such a circuit may be connected to numerous different configurations of drawbar-type organ interfaces having differing numbers of keys, switches, and drawbars, as well as stand-alone units having only keys and drawbars, only foot pedals and drawbars, or only drawbars. Embodiments of the present invention further provide a method for determining the position of each drawbar of a drawbar-type organ interface using binary logic.
