Image calibration

Arterial CO2 tension is a powerful modulator of cerebral vascular calibre, CBF and ICP (12-15.) While the mechanisms are incompletely understood, CO2 relaxes pial arterioles by interactions between the endothelium, vascular smooth muscle, pericytes, adjacent neurons and glial cells. Studies supported that cerebral vessels are sensitive to changes in extracellular pH, rather than a direct response to CO2 or bicarbonate. In the limits of physiological PaCO2, 20-60 mmHg, the relationship between PaCO2 and CBF is linear.

OpenCV (Open Source Computer Vision Library: http://opencv.org) is an open-source BSD-licensed library that includes several hundreds of computer vision algorithms. The document describes the so-called OpenCV 2.x API, which is essentially a C++ API, as opposite to the C-based OpenCV 1.x API. The latter is described in opencv1x.pdf. OpenCV has a modular structure, which means that the package includes several shared or static libraries.

This Atlas is not what it should be. If fate had been kinder, each of the four planetary bodies represented here would have had its own Atlas, each larger than this volume. Don’t blame the author, though; the culprit is an elegant yet critical device called the HGA, explained in Chapter 1.3. Should you pass over this book on your way to the used “pilates-at-home” bookshelf or toss it in the recycle paper bin? I hope not.

VSP techniques provide information in the vicinity of the borehole. VSP is a class of seismic measurements that can obtain high resolution images near the wellbore (Hardage, 2000). VSP acquisition utilizes sensors deployed within a borehole and sources located at the surface, whereas crosswell tomography uses sources and receivers both deployed in boreholes. The advantage of VSP, crosswell seismic, and other high resolution methods is to obtain more precise estimations of the CO2 induced effects on seismic properties.
