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 ...
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 ...
Comparative study between powers of sigmoid functions, MLP-backpropagation and polynomials in function approximation problems
(Proceedings of SPIE - The International Society for Optical Engineering, 1999-01-01) [Trabalho apresentado em evento]
Function approximation is a very important task in environments where the computation has to be based on extracting information from data samples in real world processes. So, the development of new mathematical model is a ...
