  • Publication number: 20110206236
    Abstract: An automated guidance system for a moving frame. The automated guidance system has an imaging system disposed on the frame; a motion sensing system coupled to the frame and configured for sensing movement of the frame; and a processor communicably connected to the vision system for receiving image data from the vision system and generating optical flow from image data of frame surrounding. The processor is communicably connected to the motion sensing system for receiving motion data of the frame from the motion sensing system. The processor is configured for determining, from kinematically aided dense optical flow correction to frame kinematic errors, due to errors in motion data from the motion sensing system.

  • Patent number: 7242421
    Abstract: A method of establishing a communications link uses automatic sensing of a computer user's presence and activity state to record user attributes in a form accessible to other computers in a communications network. Such automatic sensing may include keyboard/mouse monitors, cameras with associated image processing algorithms, speech detectors, RF radiation detectors, and infrared sensors. Preferably, the attribute recording is done in a server process which can be accessed by other computer programs. A first application of this method is to inform persons at remote locations whether the party to be called is available to receive a call. A second application of the method is to use a Connection Agent to determine whether all desired participants for a conference, or at least a quorum of them, are present and available, so that the conference can be started.

  • Patent number: 6680745
    Abstract: A videoconferencing method automatically detects, within an image generated by a camera, locations and relative sizes of faces. Based upon the detection, a control system tracks each face and keeps a camera pointed at and focused on each face, regardless of movement about a room or other space. Preferably, multiple cameras are used, and an automatic algorithm selects a best face image and resizes the face image to substantially fill a transmitted frame. Preferably, an image encoding algorithm adjusts encoding parameters to match a currently amount of bandwidth available from a transmission network. Brightness, contrast, and color balance are automatically adjusted. As a result of these automatic adjustments, participants in a video conference have freedom to move around, yet remain visible and audible to other participants.
