TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Extracting high resolution 3D models from images of textured and non-textured surfaces in an uncontrolled environment. DESCRIPTION: A primary objective of computer vision is to enable reconstructing 3D scene geometry and camera motion from a set of images [1]. Several toolsets exist that rely on a controlled collection of images from a single calibrat ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Develop novel techniques to identify and locate uncommon targets in overhead and aerial imagery, specifically when few prior examples are available. Initial focus will be on panchromatic electro-optical (EO) imagery with a subsequent extension to multi-spectral imagery (MSI) and/or synthetic aperture radar (SAR) imagery. DESCRIPTION: The National Geosp ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Develop a fast automated signal matching algorithm based on hashing algorithms. DESCRIPTION: Hashing-based algorithms for audio-matching were introduced by Shazam Entertainment, Ltd. in 2000 to help customers identify music tracks based on short audio clips collected from cell phones [1] [2]. This algorithm matches of a single clip against a massive ar ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Construct a computer vision system for synthetic aperture radar imagery (SAR) to demonstrate segmentation into terrain types. DESCRIPTION: NGA Research seeks image segmentation algorithms for SAR imagery to identify different terrain types (roads, forest, agricultural, urban). These algorithms should be robust against varying collection geometry and i ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Develop algorithms for enhancing resolution of satellite imagery from one source that leverages information from other satellite image sources that might have different resolution and different phenomenology. DESCRIPTION: Analysis of satellite imagery is always limited by image resolution. No matter what the resolution of the available imagery there i ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Develop algorithms and techniques that provide superior digital elevation data constituting the surfaces of fixed structures in urban or highly structured environments using remote sensing image data. DESCRIPTION: Current methods to produce digital elevation maps using remote sensing have difficulty in urban settings or areas with significant vertical ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Provide highly accurate foundation data of buildings and linear structures by conflating information from multiple available images and volunteered information. DESCRIPTION: Much manual labor is involved in. assessing and correcting errors in geospatial information concerning roads, railroads, buildings, and other prominent important features to produc ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Develop novel ways to update display electronics to maximize native OLED performance within exploitation displays for high-end imagery visualization needs. Design and breadboard prototype techniques that demonstrate sustaining dynamic sharp pixel edge rendering by OLED primitives with novel drive circuits, interfaced with an interoperable display port i ...

TECHNOLOGY AREA(S): Sensors OBJECTIVE: Develop robust, automated super resolution image processing techniques to use on low resolution video of objects under a changing pose. DESCRIPTION: Super resolution for image processing has been around since the 1980s and multiple techniques exist consisting of various registration, interpolation and restoration methods, with the majority of research and d ...

TECHNOLOGY AREA(S): Info Systems OBJECTIVE: Fully automate the process of extracting topographic features, such as ridge lines, peaks, skylines, and river banks, from imagery taken at near-ground levels, showing landscapes, hills, mountain ranges, and/or other topographic features. DESCRIPTION: NGA has an interest in knowing the earth, whether from satellite imagery, or imagery readily available ...
