Proceedings ArticleDOI
Edge detection using a neural network
TL;DR: An edge detection algorithm using multistate ADALINES (adaptive linear neurons) is presented, which can suppress noise effects without increasing the mask size and an application of the proposed edge detector to adaptive image restoration is presented.
Journal ArticleDOI
An HMM-based speech-to-video synthesizer
TL;DR: A novel correlation HMM model that is able to integrate independently trained acoustic and visual HMMs for speech-to-visual synthesis and allows increased flexibility in choosing model topologies for the acoustic andVisual HMMs.
Proceedings ArticleDOI
Adaptive image sequence noise filtering methods
TL;DR: Two adaptive approaches for nonstationary filtering of image sequences are presented and experimentally compared and show a very satisfactory performance taking into consideration their simplicity and computational efficiency.

Method and system for estimating motion within a video sequence
TL;DR: In this paper, a method and system for estimating the motion within a video sequence is presented, which consists of a preprocessor, a spatially adaptive pixel motion estimator, a motion boundary estimator and a motion analyzer.
Journal ArticleDOI
Bayesian symmetrical EEG/fMRI fusion with spatially adaptive priors
TL;DR: A novel symmetrical EEG/fMRI fusion method which combines EEG and fMRI by means of a common generative model using a total variation (TV) prior and a Bayesian formulation with a variational Bayesian framework to obtain a fully automatic fusion algorithm.
