Macaulay-Brown helps Air Force trim, compress data files

DAYTON, Ohio. Engineering and cybersecurity firm MacAulay-Brown has announced a new approach to thinning hyperspectral image data for evaluation by the Air Force Life Cycle Management Center (AFLCMC). Under a Cooperative Research and Development Agreement (CRADA), data thinned at different levels will be evaluated by AFLCMC for compatibility testing with existing tools used by the U.S. Air Force to analyze hyperspectral data.

MacAulay-Brown says that its Advanced Technology Group (ATG) has developed software that will manipulate hyperspectral image files that still exhibit excellent image quality at half the size, while also making use of industry standard data types. If the AFLCMC evaluation is successful, users on future projects could cut the data rate for transferring hyperspectral images in half by using just a few lines of code.

MacAulay-Brown is currently exploring a variety of approaches in and thinning, with an emphasis on simple and reliable methods that can be easily used on existing frameworks; such techniques include a thinner for formatted Portal Network Graphic (PNG) images, a new approach to steganography (the concealment of a file, image, or message inside another) that helps maintain maximum fidelity in the masking image, and possible enhancements to JPEG compression images.
