Patent number: 10140693Abstract: A computer-implemented method for ordering vertices in an image frame within a data stream, wherein the image frame corresponds to Earth-viewing data. A point of intersection of a primary pair of lines is determined and loaded into computer memory, and interrogated as to a sign of a signed remainder with respect to each of two secondary lines defined by the pairwise ordered sets of vertices. In the case of opposite remainder sign with respect to the two secondary lines, two provisional indices are swapped to obtain a rectified index for each of the four vertices. The process is repeated with respect to the signed remainder of the intersection point of the secondary lines relative to the primary lines. The four vertices are then fit, in accordance with index ordering, into a tiling of the surface of the Earth based on the rectified index of each of the four vertices.Type: GrantFiled: March 23, 2017Date of Patent: November 27, 2018Assignee: INTERGRAPH CORPORATIONInventor: Gene Arthur Grindstaff

Patent number: 8233044Abstract: A method for demultiplexing time-division multiplexed digital video data which originates from multiple sources. The video data is not indexed nor identified to the sources. A first set of digital video data representative of a first image is identified as representative video data of the first source. A second set of digital video data representative of a current image is then retrieved. A difference ratio is calculated using the representative digital video data and the current set of digital video data. If the difference ratio is above a threshold, a display query is prompted to a user to indicate the source. If the response is indicative with a new source, the current set of digital video data is stored to a second memory location associated with the second source and identified as a representative of the second source.Type: GrantFiled: December 17, 2007Date of Patent: July 31, 2012Assignee: Intergraph Software TechnologiesInventors: Gene Arthur Grindstaff, Susan Heath Calvin Fletcher, Therman Ward McKay, III

Patent number: 7477797Abstract: A method for viewing a first object that is obstructed by a second object. In such a method, the first object has a contrasting color to the second object and the second object is constructed from a material that allows visible light to pass therethrough. The amount of visible light that passes through the second object is not enough such that the first object is visible to the human eye. The method involves taking a digital image of the first and second object using a visible light sensor, such as a CCD camera sensor. The digital image data that is received into a computer system contains both first object data and second object data. It should be understood that the first object data and the second object data include color information. The amount of contrast between the first and the second object should be approximately 10% of the total scale such that on a 256 color scale the difference is approximately 25 levels.Type: GrantFiled: May 26, 2006Date of Patent: January 13, 2009Assignee: Intergraph Software Technologies CompanyInventors: Gene Arthur Grindstaff, Susan Heath Calvin Fletcher, Therman Ward McKay, III

Patent number: 7436437Abstract: A method for image stabilization of at least two digital images is disclosed. In such an embodiment, a first digital image having a plurality of pixels and at least a second image having a plurality of pixels are provided. Each pixel has an associated address for display and is representative of a color. Either a user of the system provides a color match range or the system provides a predetermined color matched range. A pixel is selected within the first digital image. Preferably the pixel is one that represents an item within the image that is either blurry due to movement of the item or appears jittery due to camera movement. Due to the vast number of available colors a pixel selected in a first image can be matched to a pixel in a second image within a range. The range allows for compensation due to lighting changes. Once the pixel in the first image is selected it can be compared to all pixels within the second image.Type: GrantFiled: September 24, 2003Date of Patent: October 14, 2008Assignee: Intergraph Software Technologies CompanyInventors: Susan Heath Calvin Fletcher, Gene Arthur Grindstaff, Therman Ward McKay, III

Patent number: 7310110Abstract: A method for demultiplexing digital video data which originates from multiple sources in which the multiplexed images are not indexed nor is there identification information provided to differentiate sources. The sources are generally cameras which may be stationary cameras or moving cameras that rotate as are commonly used in the surveillance industry. A first set of digital video data representative of a first image is retrieved from a memory source or from a video tape. The first set of digital video data is stored to a memory location associated with a first source. The first set of video data is also identified as representative video data of the first source. A second set of digital video data representative of a current image is then retrieved. A difference ratio is calculated using the representative digital video data and the current set of digital video data.Type: GrantFiled: September 6, 2002Date of Patent: December 18, 2007Assignee: Intergraph Software Technologies CompanyInventors: Gene Arthur Grindstaff, Susan Heath Calvin Fletcher, Therman Ward McKay, III
