Drift Correction in Multivariate Calibration Models Using On-line Reference Measurements

Dominique Bonvin, Michael Amrhein, Pamandeep Singh Gujral

On-line measurements from first-order instruments such as spectrometers may be compromised by instrumental, process and operational drifts that are not seen during off-line calibration. This can render the calibration model unsuitable for prediction of key ...

Non-invasive quantification of brain glycogen absolute concentration

Rolf Gruetter, Lijing Xin, Hongxia Lei, Hanne Frenkel, Sabrina Laus, Ruud van Heeswijk

The only currently available method to measure brain glycogen in vivo is C-13 NMR spectroscopy. Incorporation of C-13-labeled glucose (Glc) is necessary to allow glycogen measurement, but might be affected by turnover changes. Our aim was to measure glycog ...

Multi-system biometric authentication : optimal fusion and user-specific information

Norman Hoon Thian Poh

Verifying a person's identity claim by combining multiple biometric systems (fusion) is a promising solution to identity theft and automatic access control. This thesis contributes to the state-of-the-art of multimodal biometric fusion by improving the und ...

Evaluating Chromatic Adaptation Transform Performance

Sabine Süsstrunk

The performance of many color science and imaging algorithms are evaluated based on their mean errors. However, if these errors are not normally distributed, statistical evaluations based on the mean are not appropriate performance metrics. We present a no ...
