Visual calibration of CRT monitors
(Elsevier Science, 2001-07)
In this paper, we develop and test a technique for calibrating a computer-controlled television monitor using a visual comparison instead of a photometer. The basic principle of the calibration is to compare a patch of ...

(2019-05-08)
RESUMEN:
El estudio de transitorios electromagnéticos en líneas de transmisión es un paso
importante en la etapa de diseño de sistemas de transmisión, pues permiten
conocer las posibles sobretensiones y sobrecorrientes ...
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 ...
Implementación y aplicación de algoritmos Retinex al preprocesamiento de imágenes de retinografía color
(Biomédica, Mecatrónica y MecánicaEscuela de Ingeniería de Antioquia EIAUniversidad CES, 2014-04-24)
Diabetic retinopathy is a disease caused by complications of the retina, with progressive evolution. This pathology
is detected on the fundus eye images, which in most cases have non-uniform illumination. In this paper ...
High dynamic range imaging method for interferometry
(ELSEVIER SCIENCE BV, 2011-01-01)
We demonstrate a method to easily and quickly extend the dynamic range imaging capabilities of the camera in a typical interferometric approach. The camera dynamic range is usually low and limited to 256 gray levels. Also, ...
Femtosecond laser induced damage characterization of transmission volume phase gratings
(American Institute of Physics, 2014-07-30)
A procedure to characterize the induced damage and the incubation effects in volume transmission gratings under femtosecond laser pulse train illumination is presented. It was also developed a formalism that explains the ...
Retinal image analysis: Image processing and feature extraction oriented to the clinical task
(Sociedad Espanola de Optica, 2017)
Medical digital imaging has become a key element of modern health care procedures. It provides visual documentation and a permanent record for the patients, and most important the ability to extract quantitative information ...
E.D.R.A., the Argentine facility to simulate radiation damage in space
(Pergamon-Elsevier Science Ltd, 2019-01)
E.D.R.A. (Ensayos de Daño por Radiación y Ambiente/Test of Radiation and Environmental Damage) is a system composed of a beam line and a vacuum chamber installed at Tandar (a 20 MV Van de Graaff tandem accelerator). It has ...
