Robust and fast vowel recognition using optimum-path forest
(2010-11-08)
The applications of Automatic Vowel Recognition (AVR), which is a sub-part of fundamental importance in most of the speech processing systems, vary from automatic interpretation of spoken language to biometrics. State-of-the-art ...
Impact of interjudge agreement on perceptual judgment of hypernasality
(Universidade de São Paulo, Hospital de Reabilitação de Anomalias CraniofaciaisBauru, 2013-11-08)
Objective: To investigate the effect of perceptual interjudge agreement of hypernasality on velopharyngeal (VP) closure prediction. Methods: Two logistic regression models were developed and compared in order to verify the ...
Color description of low resolution images using fast bitwise quantization and border-interior classification
(Institute of Electrical and Electronics Engineers - IEEEBrisbane, 2015-04)
Image classification often require preprocessing and feature extraction steps that are directly related to the accuracy and speed of the whole task. In this paper we investigate color features extracted from low resolution ...
ON THE IMPORTANCE OF USING HIGH RESOLUTION IMAGES, THIRD LEVEL FEATURES AND SEQUENCE OF IMAGES FOR FINGERPRINT SPOOF DETECTION
(Ieee, 2015-01-01)
The successful and widespread deployment of biometric systems brings on a new challenge: the spoofing, which involves presenting an artificial or fake biometric trait to the biometric systems so that unauthorized users can ...

Signal classification by similarity and feature extraction with application in automatic insect identification
(Universidade Federal de Pernambuco - UFPESociedade Brasileira de Computação - SBCRecife, 2015-07)
Insects have a strong relationship with the human-beings. For example, some species of mosquito transmit diseases that kill millions of people around the world. At the same time, the presence of certain insects is essential ...
Recognition Of Occluded Facial Expressions Based On Centrist Features

Signal classification by similarity and feature extraction allows an important application in insect recognition
(Universidade de São Paulo - USPUniversidade Federal de São Carlos - UFSCarCentro de Robótica de São Carlos - CROBSociedade Brasileira de Computação - SBCSociedade Brasileira de Automática – SBASão Carlos, 2014-10)
Insects have a strong relationship with the humanity, in both positive and negative ways. It is estimated that insects, particularly bees, pollinate at least twothirds of all food consumed in the world. In contrast, mosquito ...
