Error Assessment In 3D Computer Vision
<p>Basic concepts in probability are employed to develop analytic formulae for both the expectation (bias) and variance for image motions obtained during subset-based pattern matching. Specifically, the expectation and variance in image motions in the presence uncorrelated Gaussian intensity noise …

Topics in multivariate covariance estimation and time series analysis.
… analysis (RDA) is a well-known method of covariance regularization for the multivariate-normal based discriminant function. RDA generalizes the ideas of linear (LDA), quadratic (QDA), and mean-eigenvalue covariance regularization methods into one framework. The original idea and known …

Cortical Gyrification in Methamphetamine Associated Psychosis: A Potential Neurodevelopmental Biomarker for Risk of Psychosis
… (n=21), individuals with MAP (n=18) and healthy controls (n=21). Gyrification indices were determined for each participant using Freesurfer 7.2 and compared across groups with age and sex as covariates in a multivariate analysis of co-variance (MANCOVA). The results demonstrate that group …

Estimation and prediction problems in mixed linear models for maternal genetic effects
The main objectives of this study were: (1) to compare quadratic and likelihood estimators of dispersion parameters in a sire plus maternal grandsire model (S-M) with respect to estimated bias (EB) and estimated mean squared error (EMSE) when the data are affected by selection, (2) to estimate …

Increased age leads to decreased dexterity: is it really that simple?
It is commonly believed that with increased age, movement dexterity becomes slower and increasingly clumsy when performing simple every day tasks. In the General Introduction of this PhD thesis (Chapter 1), literature that supports evidence for this relationship was reviewed. In addition, …

Time series estimation in a spiked signal regime
Working with missing or incomplete data is a universal problem in all sciences. In meteorology, temperature data streams can contain missing values due to sensor malfunctions. In geophysical remote sensing, missing data can may be attributed to irregular global sampling by an orbiting spacecraft. …
