Acquiring digital images

The superior accuracy and sensitivity of 18F-FDG-PET/CT in comparison to morphological imaging alone leads to an upstaging in up to 30% of lymphoma patients. Novel digital PET/CT scanners might enable to reduce administered tracer activity or scan time duration while maintaining diagnostic performance; this might allow for a higher patient throughput or a reduced radiation exposure, respectively.

The intervention of engineering properties of the seeds has an important role in design of pneumatic seeder for seeding in plug trays. The present study was carried out to find different physical properties like seed size (length and width), shape, thousand seed weight, bulk density and terminal velocity (aerodynamic property) of cabbage (Brassica oleracea) and tomato (Lycopersicon esculentum) seeds at moisture content of 8.24%(wb) and 9.71%(wb), respectively.

In this work, a critical review of the current nondestructive probing and image analysis approaches is presented, to revealing otherwise invisible or hardly discernible details in manuscripts and paintings relevant to cultural heritage and archaeology. Multispectral imaging, X-ray fluorescence, Laser-Induced Breakdown Spectroscopy, Raman spectroscopy and Thermography are considered, as techniques for acquiring images and spectral image sets; statistical methods for the analysis of these images are then discussed, including blind separation and false colour techniques.

The art of imaging blood vessels in the human body is called angiography. Since its inception, physicians have benefited from the field of angiography imaging. This has helped them to diagnostically treat patients with various kinds of vascular diseases. Recently, because of the technology growth in fields of acquisition techniques, such as magnetic resonance, computer tomography, digital subtraction angiography, and ultrasound, the vascular imaging research community has become very interested. But acquisition is just one side of the coin.

Colour image processing is divided into two main areas: full colour and pseudo-colour processing. In the former group, the images are normally acquired with a full colour sensor such as a CCTV camera. In the second group, a colour is assigned to a specific monochrome intensity or combination of intensities. People perceive colours that actually correspond to the nature of the light reflected from the object. The electromagnetic spectrum of the chromatic light falls in the range of 400-700 nm.

Staring at a shelf full of Photoshop books at the local bookstore, it seems that there are more special-effect “cookbooks” and technical tomes than anyone would ever care to read. The problem is that none of those “cookbooks” provide enough detail to really let you feel like you understand the program (blindly following the listed steps just doesn’t do it), and all of the technical books are deep into terms like rasters, vectors, and bit-depth settings. That’s the primary reason that most people aren’t truly comfortable with Photoshop.

Digital images and video, acquired by still cameras, consumer camcorders, or even broadcast-quality video cameras, are usually degraded by some amount of blur and noise. In addition, most electronic camerashavelimitedspatial resolutiondeterminedbythecharacteristicsof thesensorarray. Common causes of blur are out-of-focus, relative motion, and atmospheric turbulence. Noise sources include filmgrain, thermal, electronic, and quantization noise.
