Global color estimation of special-effect coatings from measurements by commercially available portable multiangle spectrophotometers.
Colors of special-effect coatings have strong dependence on illumination/viewing geometry and an appealing appearance. An open question is to ask about the minimum number of measurement geometries required to completely characterize their observed color shift. A recently published principal components analysis (PCA)-based procedure to estimate the color of special-effect coatings at any geometr...
متن کاملReproducibility in Nerve Morphometry: Comparison between Methods and among Observers
We investigated the reproducibility of a semiautomated method (computerized with manual intervention) for nerve morphometry (counting and measuring myelinated fibers) between three observers with different levels of expertise and experience with the method. Comparisons between automatic (fully computerized) and semiautomated morphometric methods performed by the same computer software using the...

متن کاملComparison of near-infrared transmittance and reflectance measurements using dispersive and Fourier transform spectrophotometers
A spectrophotometer based on an integrating sphere coupled to a commercial Fourier Transform Infrared (FTIR) instrument has been constructed for regular spectral transmittance and re ectance measurements over the 1 m m to 18 m m wavelength region. Despite the large number of sources of error that often limit the radiometric accuracy of FTIR measurements, we demonstrate uncertainties similar to...
متن کاملComparison of methods for DE-CMR infarct size quantification - reproducibility among three core labs
Background Infarct size measurements with delayed-enhancement cardiovascular magnetic resonance (DE-CMR) are being used as surrogate endpoints in acute myocardial infarction (AMI) trials comparing therapeutic strategies. Semiautomated techniques using signal intensity thresholding are thought to be more reproducible than manual planimetry to define AMI borders. For both methods, endo-/ epicardi...
