Calibration of a catadioptric omnidirectional vision system with conic mirror
Omnidirectional vision systems that enable 360° imaging have been widely used in several research areas, including close-range photogrammetry, which allows the accurate 3D measurement of objects. To achieve accurate results ...
Sensitivity, Prediction Uncertainty, and Detection Limit for Artificial Neural Network Calibrations
(American Chemical Society, 2016-08)
With the proliferation of multivariate calibration methods based on artificial neural networks, expressions for the estimation of figures of merit such as sensitivity, prediction uncertainty, and detection limit are urgently ...
A influência das injunções de orientação relativa na calibração de um sistema dual de câmaras digitais
Image acquisition systems based on multi-head arrangement of digital frame cameras, such as the commercial systems DMC, UltraCam, besides others, are attractive alternatives enabling larger imaging area when compared to a ...
Impact of Methodological and Calibration Approach on the Association of Central and Peripheral Systolic Blood Pressure with Cardiac Structure and Function in Children, Adolescents and Adults
Introduction: Peripheral and aortic systolic blood pressure (pSBP and aoSBP) were measured using different methodological and calibration approaches to analyze the association and agreement between pSBP and/or aoSBP, and ...
Toward Fail-Safe Speaker Recognition: Trial-Based Calibration with a Reject Option
(Institute of Electrical and Electronics Engineers, 2019-01)
The output scores of most of the speaker recognition systems are not directly interpretable as stand-alone values. For this reason, a calibration step is usually performed on the scores to convert them into proper likelihood ...
