An intelligent system for pavement management
(Applications and Science of Computational Intelligence, 1998-01-01) [Trabalho apresentado em evento]
This paper describes a method for the evaluation of pavement condition through artificial neural networks using the MLP backpropagation technique. Two of the most used procedures for detecting the pavement conditions were ...
Estimating crowd density with Minkowski fractal dimension
(ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings, 1999-01-01) [Trabalho apresentado em evento]
The estimation of the number of people in an area under surveillance is very important for the problem of crowd monitoring. When an area reaches an occupation level greater than the projected one, people's safety can be ...
Oriented texture classification based on self-organizing neural network and Hough transform
(ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings, 1997-01-01) [Trabalho apresentado em evento]
This paper presents a technique for oriented texture classification which is based on the Hough transform and Kohonen's neural network model. In this technique, oriented texture features are extracted from the Hough space ...
Rede neural não supervisionada baseada em transformada Karhunen-Loève para processamento, compressão e reconhecimento de imagens
(European Space Agency, (Special Publication) ESA SP, 1997-02-01) [Artigo]
The merit of the Karhunen-Loève transform is well known. Since its basis is the eigenvector set of the covariance matrix, a statistical, not functional, representation of the variance in pattern ensembles is generated. By ...
Feedforward neural networks based on PPS-wavelet activation functions
(Ii Workshop on Cybernetic Vision, Proceedings, 1997-01-01) [Trabalho apresentado em evento]
Function approximation is a very important task in environments where computation has to be based on extracting information from data samples in real world processes. Neural networks and wavenets have been recently seen ...
Function approximation by polynomial wavelets generated from powers of sigmoids
(Wavelet Applications Iii, 1996-01-01) [Trabalho apresentado em evento]
Mathematical tests about the existence and applications of PPS-wavelets in function approximation problems
(Wavelet Applications V, 1998-01-01) [Trabalho apresentado em evento]
Neural networks and wavelet transform have been recently seen as attractive tools for developing eficient solutions for many real world problems in function approximation. Function approximation is a very important task ...
A simple mechanism to deal with sequential code in dataflow architectures
(Fifth International Conference on High Performance Computing, Proceedings, 1998-01-01) [Trabalho apresentado em evento]
The aim of this work is to propose a simple and efficient mechanism to deal with the problem of executing sequential code in a pure dataflow machine. Our results is obtained with a simulator of Wolf  architecture. The ...
Utilizing the CORBA platform in the construction of a highly immersive virtual environment
(Proceedings of SPIE - The International Society for Optical Engineering, 1999-12-01) [Trabalho apresentado em evento]
This article presents the implementation of a distributed system of virtual reality, through the integration of services offered by the CORBA platform (Common Object Request Broker Architecture) and by the environment of ...
