  • Patent number: 9942481
    Abstract: Disclosed herein are systems and methods for iterative adjustment of video-capture settings based on identified persona. In an embodiment, a method includes receiving video frames that are being captured by a video camera of an ongoing scene. The method also includes identifying a persona in one or more of the received frames at least in part by identifying, in each such frame, a set of pixels classified as being representative of the persona. The method also includes selecting, based collectively on the brightness values of the pixels in the identified set, a respective adjustment command for one or more adjustable video-capture settings of the camera, as well as outputting the selected commands to the camera for use in continuing to capture video data representative of the ongoing scene.

  • Patent number: 9792676
    Abstract: A system for background image subtraction includes a computing device coupled with a 3D video camera, a processor o£ the device programmed to receive a video feed from the camera containing images of one or more subject that include depth information. The processor, for an image: segments pixels and corresponding depth information into three different regions including foreground (FG), background (BG), and unclear (UC); categorizes UC pixels as FG or BG using a function that considers the color and background history (BGH) information associated with the UC pixels and the color and BGH information associated with pixels near the UC pixels; examines the pixels marked as FG and applies temporal and spatial filters to smooth boundaries of the FG regions; constructs a new image by overlaying the FG regions on top of a new background; displays a video feed of the new image in a display device; and continually maintains the BGH.

  • Patent number: 9671931
    Abstract: Described herein are methods and systems for visually deemphasizing a displayed persona. At least one embodiment takes the form of a method carried out by a user-interface (UI)-management device. The UI-management device identifies a persona region of a displayed persona and identifies a user-interface-focus location. The UI-management device then makes a persona-deemphasize determination based on the identified persona region and the identified user-interface-focus location. In response to making the persona-deemphasize determination, the UI-management device visually deemphasizes the displayed persona.

  • Patent number: 5843768
    Abstract: A container for collecting and storing compostable waste while minimizing offensive odors and the accumulation of insect or other pests near the container by providing specially designed ventilation and drainage. As shown in FIG. 1, the enclosed volume (12) of the bucket-like portion (1) is ventilated by means of a solid ventilation shaft (4) which penetrates the sealable lid (3) and passes air to and from the drainage chamber (7) below the suspended floor (5). Air below the suspended floor (5) circulates through ventilation/drainage holes (6) and the enclosed volume (12) and the contained waste. The circulating air maintains aerobic conditions in the waste thus minimizing offensive odors that would accompany anaerobic conditions. Water is allowed to drain from the waste through the ventilation/drainage holes and collect in the drainage chamber (7) below the suspended floor (5), where it cannot contribute to anaerobic conditions in the waste.
