A New Periocular Dataset Collected by Mobile Devices in Unconstrained Scenarios
Luiz A. Zanlorensi, Rayson Laroca, Diego R. Lucio +3
Recently, ocular biometrics in unconstrained environments using images obtained at visible wavelength have gained the researchers' attention, especially with images captured by mob…
A Comprehensive Comparison of End-to-End Approaches for Handwritten Digit String Recognition
Andre G. Hochuli, Alceu S. Britto, David A. Saji +3
Over the last decades, most approaches proposed for handwritten digit string recognition (HDSR) have resorted to digit segmentation, which is dominated by heuristics, thereby impos…
Intrapersonal Parameter Optimization for Offline Handwritten Signature Augmentation
Teruo M. Maruyama, Luiz S. Oliveira, Alceu S. Britto +1
Usually, in a real-world scenario, few signature samples are available to train an automatic signature verification system (ASVS). However, such systems do indeed need a lot of sig…
Single-sample writers -- "Document Filter" and their impacts on writer identification
Fabio Pinhelli, Alceu S. Britto, Luiz S. Oliveira +2
The writing can be used as an important biometric modality which allows to unequivocally identify an individual. It happens because the writing of two different persons present dif…
Two-View Fine-grained Classification of Plant Species
Voncarlos M. Araujo, Alceu S. Britto, Luiz E. S. Oliveira +1
Automatic plant classification is a challenging problem due to the wide biodiversity of the existing plant species in a fine-grained scenario. Powerful deep learning architectures…
An End-to-End Approach for Recognition of Modern and Historical Handwritten Numeral Strings
Andre G. Hochuli, Alceu S. Britto, Jean P. Barddal +2
An end-to-end solution for handwritten numeral string recognition is proposed, in which the numeral string is considered as composed of objects automatically detected and recognize…
CNN Hyperparameter tuning applied to Iris Liveness Detection
Gabriela Y. Kimura, Diego R. Lucio, Alceu S. Britto +1
The iris pattern has significantly improved the biometric recognition field due to its high level of stability and uniqueness. Such physical feature has played an important role in…
Continuous Emotion Recognition via Deep Convolutional Autoencoder and Support Vector Regressor
Sevegni Odilon Clement Allognon, Alessandro L. Koerich, Alceu de S. Britto
Automatic facial expression recognition is an important research area in the emotion recognition and computer vision. Applications can be found in several domains such as medical t…
