A graph-based framework for thermal faceprint characterization
(Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 2011-09-26) [Trabalho apresentado em evento]
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 ...
An intelligent system to detect drilling problems through drilled cuttings return analysis
(SPE/IADC Drilling Conference, Proceedings, 2010-07-07) [Trabalho apresentado em evento]
Cuttings return analysis is an important tool to detect and prevent problems during the petroleum well drilling process. Several measurements and tools have been developed for drilling problems detection, including mud ...
Optimum-Path Forest Classifier for Large Scale Biometric Applications
(2012 Third International Conference on Emerging Security Technologies (est), 2012-01-01) [Trabalho apresentado em evento]
This paper addresses biometric identification using large databases, in particular, iris databases. In such applications, it is critical to have low response time, while maintaining an acceptable recognition rate. Thus, ...
Robust and fast vowel recognition using optimum-path forest
(ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings, 2010-11-08) [Trabalho apresentado em evento]
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 ...
A Fast Large Scale Iris Database Classification with Optimum-Path Forest Technique: A Case Study
(2012 International Joint Conference on Neural Networks (ijcnn), 2012-01-01) [Trabalho apresentado em evento]
Majority of biometric researchers focus on the accuracy of matching using biometrics databases, including iris databases, while the scalability and speed issues have been neglected. In the applications such as identification ...
Automatic visual dictionary generation through optimum-path forest clusteringautomatic visual dictionary generation through optimum-path forest clustering
(2012 Ieee International Conference On Image Processing (icip 2012), 2012-01-01) [Trabalho apresentado em evento]
Image categorization by means of bag of visual words has received increasing attention by the image processing and vision communities in the last years. In these approaches, each image is represented by invariant points ...
