dimensional information many different ways. However, in this study, we will focus on binocular stereo, two cameras in gives a right and left images used. In the following, it is assumed that the camera uses internal and external calibration. Camera intrinsic parameters including focal length, ...
They are therefore well suited to long linear and two-dimensional infrared arrays. Systems based upon such focal planes can be made smaller, lighter, with lower power consumption and can result in much higher performance than systems based on first generation detectors. During the past two decades...

18 The PPG index provides a quantitative classification of the spatial distribution of CAD based on the magnitude of pressure drop over 20 mm and the extent of functional disease according to the following formula:PPG index={maximumΔFFR in20mmΔFFR in target vessel+[1−length with FFR drop...
The approach involves one- or two-dimensional space scanning and a deconvolution operation, which enable evaluations of the size and spatial distribution of the focal spot formed by a single-photon-level pulsed laser. The results indicate that the average full width at half maximum of the focal ...
