  • Methods for processing images to detect objects below the surface of the water
    Patent number: 7869620
    Abstract: The present invention is a processing method to increase the detection of objects below the surface of the water comprising the steps of: acquiring image data in separate spectral regions simultaneously and converting the image data into intensity value arrays for each spectral region, transforming the intensity value arrays into two-dimensional discrete wavelet transform arrays for each spectral region, and subtracting in a pair wise manner the two-dimensional discrete wavelet transform arrays thereby obtaining images showing an object below the surface of the water.

  • Multispectral imaging system and methods of use
    Patent number: 7474334
    Abstract: The multispectral imaging system provides detection of low contrast objects on or below the surface of a body of water through the elimination of most of the surface reflected light clutter components from multispectral images. The images are processed by taking the weighted difference of two or more spectral components and applying a demeaning or whitening filter to the result. The images can then be frame averaged where the appropriate corrections for motion, magnification, rotation, and translation have been applied. The resultant imagery can then be displayed to an operator or transmitted to a remote location.
