  • Publication number: 20140145936
    Abstract: A method for 3D gesture behavior recognition is disclosed, which includes detecting a behavior change of one or more attendees at a meeting and/or conference; classifying the behavior change; and performing an action based on the behavior change of the one or more attendees. Another method, system and computer readable medium for 3D gesture behavior recognition as disclosed, includes obtaining temporal segmentation of human motion sequences for one or more attendees; determining a probability density function of the temporal segmentations of the human motion sequences using a Parzen window density estimation model; computing a bandwidth for determination of a median absolute deviation; updating the Parzen window to adapt for changes in the motion sequences for the one or more attendees; and detecting actions based.

  • Patent number: 7636105
    Abstract: The method and apparatus for providing motion control signals between a fixed lens static camera and a PTZ camera that includes an adjustable-in-use focal length adapted to provide improved surveillance. In one aspect of the present invention, the improved method and apparatus includes an improved PTZ process in which fuzzy logic based information is utilized to achieve a set of more reliable P/T/Z parameters. In another aspect of the invention, the fixed lens static camera and the PTZ camera are mounted vertically on top of each other. In another aspect of the present invention, there is provided an automatic self-calibration between the fixed lens static camera and the PTZ camera. In another aspect of the present invention, there is provided a cost-effective standalone single board DSP solution.
