Patent number: 8542924Abstract: 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.Type: GrantFiled: July 1, 2012Date of Patent: September 24, 2013Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Cheryl A. Blain, Carolus M. Cobb, Alan Weidemann

Publication number: 20130223757Abstract: 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.Type: ApplicationFiled: April 4, 2013Publication date: August 29, 2013Applicant: The United States of America, as represented by the Secretary of the Navy, Chief of NavalInventors: Weilin Hou, Alan Weidemann

Patent number: 8437569Abstract: 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.Type: GrantFiled: May 14, 2012Date of Patent: May 7, 2013Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Weilin Hou, Alan Weidemann
