Not satisfied with the pictures you get with your 35-mm camera? Now there is a software program that lets you fix the pictures that don't capture all the visual quality and color intensity that your eyes see. The software is based on Retinax Image Processing—technology originally developed for remote sensing of the Earth by researchers at NASA's Langley Research Center and at Science and Technology Corp. "Current technology like that found in Adobe's PhotoShop software makes adjustments in gain, contrast, and other variables," says Glenn Woodell, an engineering technician and co-inventor of image processing software. "The difference with ours is that we not only look at the pixel, we also look at pixels around a given pixel." Woodell also says that colors are context dependent. "A given color, say green, surrounded by blue will look different than that same green when it is surrounded by red," he says. The software automatically makes corrections, but also allows manipulation of the image by the end user. The inventors—Woodell, Dan Jobson, and Zia ur Rahman—believe that existing image enhancement tools are either too tedious or insufficiently powerful compared to theirs. The software is currently licensed to TruView Imaging Co. "We think there are applications for the software in medical imaging, forensics, security, recognizance, mining, assembly, and many other industrial applications," says Rahman, who works for TruView. The company will make a software product available for home, professional, and industrial use by the end of the year.

This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
