A closer look at our ancestor
Discovered in 1974, the 3.2-million-year-old bones of the fossil Lucy could give us more insight into our origins. Lucy’s remains, which are the oldest and most complete adult erect-walking skeleton ever found, consist of around 80 separate bones. The fossil has been studied extensively, but questions about the way she walked and stood, and about whether she climbed trees, have gone unanswered. On her current tour of the US, Lucy took some time out from her busy museum schedule to be imaged.

Skeletal elements of the ancient fossil Lucy are assembled for display. Image courtesy of the Houston Museum of Natural Science.

RESIZING IMAGES
Available in an expanded edition, the e-book A Basic Guide to Resizing Digital Images is a practical illustrated guide to resizing (up- and downsizing, enlarging and shrinking) digital images that are stored in bit-map or raster formats, including image formats such as jpeg, gif, tiff and png. It includes step-by-step instructions and the formulas needed to resize digital images to specific requirements. Among the areas covered are color depth; visual acuity; spatial resolution; digital scanning resolution; image resampling techniques; image resizing software applications, and pixels, resolution and image size. A new section discusses how to apply theory to achieve specific resizing goals. Andrew Reid; Imaging Associates International,...]]>

MATH, DIGITAL IMAGES
The volume Mathematics of Digital Images: Creation, Compression, Restoration, Recognition explains the mathematics needed to carry out various aspects of digital imaging through examples, exercises with solutions, pseudocode and sample calculations on images. Suitable for a course or tutorial, the 866-page book is targeted to those working in machine vision, remote sensing, image processing, computer vision, and biomedical imaging or diagnosis. It covers plane geometry, pattern-generating symmetries, 3-D rotation and reflection matrices, and discrete and continuous Fourier transform. References are provided. S.G. Hoggar; Cambridge University Press, UK, 2006; $80.]]>

Frame Grabbers Fine-Tune Machine Vision
Frame grabbers convert video images from cameras into digital format and transfer these digital images to PCs, which use the converted data to make decisions about the objects being inspected. Although performing these functions quickly and reliably is critically important to the success of machine vision inspection, frame grabbers are much more than mere data converters and transfer conduits. They offer a range of capabilities that can compensate for poor lighting, optics and ways that camera sensors present information to them. This increases the quality of the images acquired and, ultimately, helps the machine vision system perform more reliable inspections.

High-performance frame grabbers like Coreco Imaging’s X64-CL can help...]]>
