Multimodal Biometric Recognition

The objectives of this research work are:

  • Evaluate state-of-the-art technologies for speaker recognition.
  • Investigate multimodal fusion techniques.
  • Develop and test a prototype of a speaker recognition system.
  • Integrate speaker recognition into the face recognition prototype existing in Computer Vision Laboratory – LVC.

Brazilian Visualization Network – Geoinformation

The Brazilian Visualization Network (RVA), whose general coordination is under the Brazilian National Laboratory of Scientific Computation (LNCC), is part of the Brazilian Technology System (SIBRATEC) of the Ministry of Science, Technology and Information (MCTI). The RVA aims at the integration of the academy to foster the innovation and creation of new markets for technological products and services. Beyond LNCC, the RVA involves the following institutions:  PUC-Rio, PUC-RS, UFRS, UFPE, UFPB, INPE, USP, UFRJ e UNICAMP, whereby LNCC, UFRJ, PUC-RS, UFPE, USP and PUC-Rio constitute the so called Coordination Nucleus of RVA.


The project “Tools for Open Multi-Risk Assessment using Earth Observation Data” (TOLOMEO) is funded under the Marie Curie International Research Staff Exchange Scheme (PIRSES-GA-2009) with the ultimate goal to establish an international cooperation between partners in Europe and South-America focused on the development of free tools for remotely sensed data analysis.

Video Surveillance

This project aims to develop technology of video surveillance with automatic facial identification, developing facial recognition techniques from video sequences that integrate methods and tools that allow:

  • To detect and track faces in real time based on video sequences,
  • To extract frontal facial images in real time based on video sequences, with good quality for recognition,
  • To build a prototype of automatic video monitoring.

The general objective of this project is the development of an automatic method to monitor the horizontal and vertical change of urban settlements and forests in Brazil. The selected test area is Rio de Janeiro, because in Rio such changes take place at a rapid pace, and data necessary to carry out the project such as aerial imagery, GIS census and topographic data, can be made available to the project through local contacts.
