    摘要: A method is presented for enhancing an image from an initial image, comprising computing a first luminance level frequency distribution corresponding to plurality of pixel constructing said initial image, representing said first luminance level frequency distribution as a resultant of Gaussian model mixtures to assess relative utilization of overall luminance level across said initial image, computing a desired luminance level frequency distribution as a function of the relative utilization, computing a transfer function to adjust the first luminance level frequency distribution to an enhanced luminance level as a function of desired level frequency distribution estimation, and applying said transfer function globally to said initial image to provide an enhanced image is. The first luminance level can be adapted to be linearized in a logarithmic form. In one embodiment, the model comprises one or more Gaussian functions. The initial image can be a background image estimated from a sequence of images.

    摘要: A method for capturing surveillance images includes of a secured area has a first camera with a first field of view and a second camera with a second field of view. An optical center is determined for the second field of view. A magnification ratio is determined between a target located in the first field of view relative to the second field of view. A pan and tilt model is determined that provides a relationship between a first camera coordinates and pan and tilt values to position the second camera at the optical center. A target is captured in the first field of view and the second camera is controlled to record the target in the second field of view with the second field of view being an enhanced view relative to the first field of view.

    摘要: A multi-sensor method and system for imaging and inspecting a storage tank that holds a liquid. The system includes an infrared sensor including a scanning vertical mount positioned outside the storage tank, an ultrasonic sensor array positioned outside the storage tank, and at least one of an ultrasonic sensor positioned inside the storage tank and a phased array radar positioned inside the storage tank secured to an interior top surface of the storage tank. The system further includes a processor coupled to receive multi-sensor data from the infrared sensor, ultrasonic sensor array and at least one of the ultrasonic sensor in the tank and the phased array radar. The processor fuses the multi-sensor data to generate a sludge level image profile for sludge in the storage tank, a liquid level image for liquid in the storage tank, and optionally an integrity profile for a shell of the storage tank.

    摘要: A method of operating an industrial plant having processing units that includes a wireless network including a network server, at least one router, and a plurality of workers including a first worker. A first handheld computing device is provided having a wireless transceiver and a processor programmed to implement a location-based service algorithm stored in non-transitory machine readable storage to a first worker. The location-based service algorithm implements obtaining location information that identifies a physical location for the first worker, and adding the location information to wireless transmissions of information by the first worker to others of the plurality of workers or to the network server. The first handheld computing device wirelessly receives server provided plant information that is a function of the physical location, and the first worker performs at least one action guided at least in part by the server provided plant information.
