Non-parametric bayesian measurement noise density estimation in non-linear filtering
In this study, we investigate online Bayesian estimation of the measurement noise density of a given state space model using particle filters and Dirichlet process mixtures. Diri...

An Anthropometric Face Model Using Variational Techniques
We describe a system that automatically generates varied geometric models of human faces. A collection of random measurements of the face is generated according to anthropometric ...

A perceptual metric for blind measurement of blocking artifacts with applications in transform-block-based image and video codin
In this paper, we analyze the formation of blocking artifacts as a result of quantization of the discrete cosine transform (DCT) coefficients. These artifacts are known to be the ...

Cross-Product Functional Coverage Measurement with Temporal Properties-Based Assertions
Temporal specification languages provide an efficient way to express events comprised of complex temporal scenarios. Assertions based on these languages are used to detect viola...
