Latest Patents

One of his latest patents focuses on location determination in a GPS-denied environment with user annotation. This patent describes systems and methods for determining a geographic location from an image captured on a mobile device, even without GPS, network access, or peripheral devices. The process involves obtaining open-source data indicative of the earth's surface, which can be combined into grids or regions. Elevation data is utilized to create skyline models at grid points on the surface. Users can trace the skyline of the environment depicted in the image, and this annotation is used to create reduced regions for edge detection analysis. The edge detection analysis identifies the skyline, which is then compared to the skyline models to determine the most likely location of the user.
