    HyperVise: v1 Build 2

    HyperVISE, developed by LPA Systems, Inc., supplies image analysis capabilities for Multi/Hyperspectral imagery. HyperVISE is designed to provide non-scientific users with the ability to use high performance image analysis techniques without full understanding of complex algorithms. HyperVISE is compatible with GV™3.0 build 940f and up. Features include:

    • Band Reduction – presents the user with a set of rudimentary choices to reduce the data set size by eliminating bands in the image.
    • Band Aggregation – creates a new image based on known techniques for combining bands of a Multi/Hyperspectral image to enhance or suppress specific features of an image.
    • Reed-Xiaoli (RX) Anomaly Detector – identifies pixels that contain spectral information significantly different from the specified reference background.
    • Spectral Match Filter – identifies portions of an image that are similar to a given spectral signature.
    • Constant False Alarm Rate (CFAR) Automatic Target Cuer – applied to the Reed-Xiaoli or Spectral Match Filter magnitude map output to highlight specific portions of the image for further investigation.
    • Empirical Line Method (ELM) Atmospheric Correction – capability that allows users to eliminate the effects of the atmosphere in an image.
    • Pixel Classifier – utilizes K-Means Pixel Classification to categorize similar-pixels in a scene.
    • Local Spectral Signature Library – allows users to use the SMF algorithm with spectral signatures from existing libraries or other images after the image has been atmospherically corrected.
    • Spectral Signature Utility – allows users to quickly view and compare spectral values.

    Required Platform
    HyperVISE is a Java-based, platform independent plugin for GV™3.0 build 940f and requires GV™3.0 to be installed prior to installing HyperVISE. Currently, testing has been performed on Windows systems. Support for other operating systems (Solaris, Linux, Mac OS X, OpenVMS) can be accomplished for specific customers.  For further technical assistance, contact
