Comprehensive Software Eases Air Traffic Management

Gridlock, bottlenecks, bumper-to-bumper jams—we all get caught in congestion at one time or another, as the rigors of road traffic are an inevitable part of life. Sometimes we do our best to get ahead, taking advantage of the slightest opening in the next lane, in anticipation that it is moving quicker than the snail’s pace of our current position. Other times, we just patiently ride it out, opting to sit back and get comfortable, fully surrendering to the sea of cars and trucks ahead.

Hierarchical Segmentation Enhances Diagnostic Imaging

Developed by Dr. James Tilton, a computer engineer with Goddard Space Flight Center’s Computational and Information Sciences and Technology Office, Hierarchical Segmentation (HSEG) software allows for advanced image analysis. The software organizes an image’s pixels into regions based on their spectral similarity, so rather than focusing on individual pixels, HSEG focuses on image regions—and how they change from a coarse-to-fine perspective. These regions (segmentations) are at several levels of detail (hierarchies) in which the coarser segmentations can be produced from the finer-resolution segmentations by selective merging of regions. In addition, the segmentation hierarchies provide analysis clues through the behavior of the image region characteristics over several levels of segmentation detail. Thus, by enabling region-based analysis, the segmentation hierarchies organize image data in a manner that makes an image’s information content more accessible.

Hand-Held Instrument Fights Acne, Tops Over-the-Counter Market

When the U.S. Congress created NASA in 1958, it sought to ensure that the Nation saw returns on its investments in aerospace research. It, therefore, wrote provisions into the Space Act Agreement that formed the Agency requiring that NASA share its technological advances and engineering expertise with the American public. Since that time, the NASA scientific prowess that sends people and equipment up into space has also come back down to Earth, in the form of products and processes that make everyday life better all around the globe.
