Surface-enhanced resonance Raman scattering: Single-molecule detection in a Langmuir-Blodgett monolayer
(Soc Applied Spectroscopy, 2003-06-01)
Surface-enhanced resonance Raman scattering (SERRS) is used for single-molecule detection from spatially resolved 1-mum(2) sections of a Langmuir-Blodgett (LB) monolayer deposited onto a Ag film. The target molecule, his ...
Image enhancement by spatial frequency post-processing of images obtained with pupil filters
(Elsevier Science, 2016-06)
The use of apodizing or superresolving filters improves the performance of an optical system in different frequency bands. This improvement can be seen as an increase in the OTF value compared to the OTF for the clear ...
A multiscale directional operator and morphological tools for reconnecting broken ridges in fingerprint images
(Pergamon-elsevier Science LtdOxfordInglaterra, 2008)
Multiple imaging radiography at LNLS
(ELSEVIER SCIENCE BVAMSTERDAM, 2008)
An analyzer-based X-ray phase-contrast imaging (ABI) setup has been mounted at the Brazilian Synchrotron Light Laboratory (LNLS) for multiple imaging radiography (MIR) purposes. The algorithm employed for treating the MIR ...
Enhancement of Breast Periphery Region in Digital Mammography
(Spie-int Soc Optical Engineering, 2018-01-01)
Volumetric breast density has been shown to be one of the strongest risk factor for breast cancer diagnosis. This metric can be estimated using digital mammograms. During mammography acquisition, breast is compressed and ...
