Using Posterior-Based Features in Template Matching for Speech Recognition

Given the availability of large speech corpora, as well as the increasing of memory and computational resources, the use of template matching approaches for automatic speech recognition (ASR) have recently attracted new attention. In such template-based ap ...

Comparing daylighting performance assessment of buildings in scale models and test modules

Marilyne Andersen, Jean-Louis Scartezzini, Anothai Thanachareonkit

Physical models are commonly used to assess daylighting performance of buildings using sky simulators for purpose of research as well as practice. Recent studies have pointed out the general tendency of scale model assessments to overestimate the performan ...

An Auxiliary Variational Method

Variational methods have proved popular and effective for inference and learning in intractable graphical models. An attractive feature of the approaches based on the Kullback-Leibler divergence is a rigorous lower bound on the normalization constants in u ...

Fast Texture-Based Tracking and Delineation Using Texture Entropy

Pascal Fua, Seyed Ali Shahrokni

We propose a fast texture-segmentation approach to the problem of 2-D and 3--D model-based contour tracking, which is suitable for real-time or interactive applications. Our approach relies on detecting texture boundaries in the direction normal to the con ...

High-order accurate methods for time-domain electromagnetics

Jan Sickmann Hesthaven

We discuss the formulation, validation, and parallel performance of a high-order accurate method for the time-domain solution of the three-dimensional Maxwell's equations on general unstructured grids. Attention is paid to the development of a general disc ...

Cristal composite SLAB pompé latéralement par diodes laser

This work presents the development of an original concept of a side pumped diode pumped crystal laser for the generation of a high power near diffraction limited beam for material processing applications such as cutting, marking and drilling. An approach b ...

Wavelet-based texture retrieval using generalized Gaussian density and Kullback-Leibler distance

Martin Vetterli, Minh Do

We present a statistical view of the texture retrieval problem by combining the two related tasks, namely feature extraction (FE) and similarity measurement (SM), into a joint modeling and classification scheme. We show that using a con- sistent estimator ...

Rotation invariant texture characterization and retrieval using steerable wavelet-domain hidden Markov models

Martin Vetterli, Minh Do

We present a new statistical model for characterizing texture images based on wavelet-domain hidden Markov models. With a small number of parameters, the new model captures both the subband marginal distributions and the dependencies across scales and orie ...
