  • Quality metric for compressed video
    Patent number: 10182233
    Abstract: Methods and systems are disclosed for calculating and applying a VQ metric which operates during the decoding of compressed video. As such, this metric is appropriate for all formats of compressed video codecs (e.g., MPEG-2, AVC and HEVC). The VQ metric relies on the decoded quantization parameter (Qp) together with analysis of both the compressed and decoded video. As such, the VQ metric does not require a reference video, and is less cumbersome to use for multiple channels, e.g., statistically multiplexed channels.
    Type: Grant

    Date of Patent: January 15, 2019

  • Method and system for enhanced portal security through stereoscopy
    Patent number: 7623674
    Abstract: Enhanced portal security is provided through stereoscopy, including a stereo door sensor for detecting and optionally preventing access violations, such as piggybacking and tailgating. A portal security system can include a 3D imaging system that generates a target volume from plural 2D images of a field of view about a portal; and a processor that detects and tracks people candidates moving through the target volume to detect a portal access event.
