  • Patent number: 8983222
    Abstract: A computer-implemented method for automatically retrieving information regarding optical properties of a scattering medium including receiving a first digital image and a first image quality value associated with the first digital image and sharpness of an edge of the first digital image, producing an optimized image, transforming the optimized image into an optimized optical transfer function, receiving a second digital image and a second image quality value associated with the second digital image and sharpness of an edge of the second digital image, identifying either the first or second digital image as an optimized digital image, and transforming the optimized optical transfer function into an optimized value of the optical parameter.

  • Patent number: 8676555
    Abstract: System and method for extraction and processing of river bank coordinates from imagery, generation of an unstructured mesh of the river using river bank positions and available or synthetic bathymetry, application of upstream and downstream boundary forcing data, contingencies for handling missing data, and configuration of multiple realizations of the developed river model.

  • Patent number: 8542924
    Abstract: A computer-implemented method for creating an ordered set of boundary data by transforming data from remotely sensed imagery of shorelines is provided. A feature data set and an edge data set are transformed into a set of 3-point boundary segments having a specific head and tail point and the segments are ordered from tail to head in a clockwise or counterclockwise manner relative to the water. Once the 3-point segments are created they are easily linked together into larger segments. These large multi-point segments in turn are linked together to create a closed loop in a predetermined direction, for example, but not limited to, the shorelines for rivers or coastal areas.

  • Publication number: 20130223757
    Abstract: A method for calculating an image quality metric for evaluating the quality of a digital image including the steps of denoising the data of the image, identifying edges in the denoised data, determining an edge profile of the edges, determining a grayscale angle for each identified edge in the edge profile that is associated with the edge, and calculating the image quality metric based on a weighted average of the grayscale angles for all the edges.

  • Patent number: 8437569
    Abstract: A method for simultaneously optimizing a digital image taken in or through a scattering medium and obtaining information regarding optical properties of the scattering medium is provided. Digital image data are received by a computer. The digital image is evaluated according to an objective image quality metric and a resulting image quality value is compared to a previously stored image quality value for the image. A revised optical transfer function is derived by modeling the optical properties of the medium to be used to generate a restored digital image, which is derived from the original image and the revised optical transfer function. The restored digital image is evaluated according to the objective image quality metric and an optimized restored image is identified. The optical properties associated with the optical transfer function producing the optimized restored image represent a close approximation of the true optical properties of the medium.
