Journal ArticleDOI
Multiply sectioned bayesian networks and junction forests for large knowledge-based systems
TL;DR: In this article, the authors derive reasonable constraints that enable a natural partition of a domain and its representation by separate Bayesian subnets, such that evidential reasoning takes place at only one of them at a time; and marginal probabilities obtained are identical to those that would be obtained from the homogeneous network.
Journal ArticleDOI
Optimal Edge Detector Design I: Parameter Selection and Noise Effects
TL;DR: This paper comments on the optimality of the Laplacian of a Gaussian edge detection filter which localizes edges through zero crossings in the filtered image by applying the filter to two ideal periodic edge models blurred by aGaussian distribution point-spread function.
Journal ArticleDOI
Paper: Multiply sectioned Bayesian networks for neuromuscular diagnosis
TL;DR: This paper presents nonmathematically the major knowledge representation issues that arose in the development of PAINULIM, a prototype neuromuscular diagnostic system based on Bayesian networks.
Journal ArticleDOI
Optimal Edge Detector Design II: Coefficient Quantization
TL;DR: The design and implementation of the Laplacian of a Gaussian edge detection filter which localizes edges through zero crossings in the filtered image is described and accuracy in the presence of noise has been found to be proportional to the square root of the filter's standard deviation.
Journal ArticleDOI
A New Method for Obtaining Accurate Estimates of Vocal-Tract Filters and Glottal Waves From Vowel Sounds
TL;DR: Unbiased vocal-tract-filter estimates are obtained from sustained vowel sounds, for which the glottal waveforms are periodically stationary random processes.
