Online Signature Verification: Improving Performance through Pre-classification Based on Global Features
(Springer, 2013-09)
In this paper, a pre-classification stage based on global features is incorporated to an online signature verification system for the purposes of improving its performance. The pre-classifier makes use of the discriminative ...
A contribution for single and multiple faces recognition using feature-based approaches
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2013-06-28)
Among biometric recognition systems, face biometrics plays an important role in research activities and security applications since face images can be acquired without any knowledge of individuals. Nowadays a huge amount ...
Region-based image retrieval using color and texture features on irregular regions of interest
(Institute of Electrical and Electronics Engineers Inc., 2015)
The Content-based image retrieval (CBIR) systems and their application in different areas of development, are current research topics, however many of this systems are likely to fail due to use global features which cannot ...
Global, semi-global and local color angular features for unsupervised face recognition
(Curitiba, 2003)
In face recognition applications, dealing with images under different conditions is a challenging task because they can affect dramatically the recognition performance. Among many image features, color is an useful feature ...
