Predicting and estimating the accuracy of n-occular optical tracking systems
Marker-based optical tracking systems are widely used in augmented reality, medical navigation and industrial applications. We propose a model for the prediction of the target reg...

Quantification of Measurement Error in DTI: Theoretical Predictions and Validation
The presence of Rician noise in magnetic resonance imaging (MRI) introduces systematic errors in diffusion tensor imaging (DTI) measurements. This paper evaluates gradient directio...
