Context Connectionist Probability Estimation in a Hybrid Hidden Markov Model-Neural Net Speech Recognition Systems
In this paper we present a training method and a network architecture for estimating context-dependent observation probabilities in the framework of a hybrid hidden Markov model (HMM) / multi layer…

A stability analysis of the fundamental matrix
The Fundamental matrix is a key concept when working with uncalibrated images and multiple viewpoints. It contains all the available geometric information and enables to recover the epipolar geometry from…

Self-calibration of an uncalibrated stereo rig from one unknown motion
We address in this paper the problem of self-calibration and metric reconstruction (up to a scale) from one unknown motion of an uncalibrated stereo rig.
-
An optimization framework for efficient self-calibration and motion determination
In this paper, we propose an alternative method to compute at the same time camera calibration and motion, which is robust and efficient.

On the direct determination of epipoles: a case study in algebraic methods for geometric problems
Studies experimentally the problem of computing the position of the epipoles in a pair of uncalibrated images; three families of methods are successively considered.

Incorporating linguistic features in a hybrid HMM/MLP speech recognizer
We propose two schemes for incorporating distinctive speech features (sonorant, fricative, nasal, vocalic, and voiced) into the MLP component of our system. We show a small improvement in recognition performance…
