Image enhancement for a low cost TEM acquisition system
(UR. FING, 1998)
This paper describes a method for the improvement of biological images acquired using a Transmission Electronic Microscope (TEM). Several techniques are presented that deal with noise reduction, artifact removal and ...
Melhoria nas condições de iluminação do acervo da Biblioteca Central da Universidade Federal de Santa Maria
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2004-10-02)
An illumination system for the underground floor - West, East, North and
South Wings - of the Main Library of the Federal University of Santa Maria is
proposed, based on Iluminância de Interiores (NBR 5413) and ...
On the illumination compensation of retinal images by means of the bidimensional empirical mode decomposition
(SPIE, 2015)
Retinal images are used for diagnostic purposes by ophthalmologists. However, despite controlled conditions in acquisition retinal images often suffer from non-uniform illumination which hinder their clinical use. In this ...
Automatic face interpretation using fast 3D illumination-based AAM models
(Elsevier Inc., 2011)
Flash image enhancement via ratio-log image translation to ambient images
(Universidad Católica San PabloPE, 2021)
To illuminate low-light scenarios in photography, photographers usually use
the camera flash, this produces flash images. Nevertheless, this external
light may produce non-uniform illumination and unnatural color of ...
Hydrothermal model for small-scale linear Fresnel absorbers with non-uniform stepwise solar distribution
(Elsevier, 2018-08)
The study of the hydrothermal behaviour of water-steam is a key topic in direct steam generation through solar concentrators. The hydrothermal behaviour is affected by the non-uniformity in the solar flux distribution along ...
Light intensity independence during dynamic laser speckle analysis
(Elsevier Science, 2016-05)
We explore some different normalizations of current dynamic laser speckle activity measures searching for their performance with respect to the illumination inhomogeneity of the samples. Inertia Moment and Average Value ...
A study of beamforming and beamshaping techniques for uniformly and non-uniformly spaced arrays
(Universidade Federal do PampaUNIPAMPAMestrado Acadêmico em Engenharia ElétricaBrasilCampus Alegrete, 2018)
