A comparative study of thermal face recognition methods in unconstrained environments
The recognition of faces in unconstrained environments is a challenging problem. The aim of this work is to carry out a comparative study of face recognition methods working in the thermal spectrum (8-12 mu m) that are ...
Feature selection for face recognition based on multi-objective evolutionary wrappers
Feature selection is a key issue in pattern recognition, specially when prior knowledge of the most discriminant features is not available. Moreover, in order to perform the classification task with reduced complexity and ...
Compressing arrays of classifiers using Volterra-Neural Network: application to face recognition
Model compression is required when large models are used, for example, for a classification task, but there are transmission, space, time or computing constraints that have to be fulfilled. Multilayer Perceptron (MLP) ...
On the Evaluation of Tensor-Based Representations for Optimum-Path Forest Classification
Tensor-based representations have been widely pursued in the last years due to the increasing number of high-dimensional datasets, which might be better described by the multilinear algebra. In this paper, we introduced a ...
A graph-based framework for thermal faceprint characterization
Thermal faceprint has been paramount in the last years. Since we can handle with face recognition using images acquired in the infrared spectrum, an unique individual's signature can be obtained through the blood vessels ...
Improving face recognition with multispectral fusion and support vector machines
(Universidade Estadual Paulista (UNESP), 2009-06-19)
O reconhecimento facial é uma das principais formas de identificação humana. Apesar das pesquisas em reconhecimento facial automático terem crescido substancialmente ao longo dos últimos 35 anos, identificar pessoas a ...
Sign language recognition model combining non-manual markers and handshapes
People with disabilities have fewer opportunities. Technological developments should be used to help these people to have more opportunities. In this paper we present partial results of a research project which aims to ...
