International Journal of Electrochemical Science, 2012 The use of digital image correlation for optical monitoring of corrosion processes occurring in a metallic sample is here proposed. The formation and reduction of corrosion products (oxides) over the surface of an old copper coin immersed in an ...

Spatially-resolved volume monitoring of adhesive cure using correlated-image optical coherence tomography [PDF]
, 2013 Cross-correlation of optical coherence tomography (OCT) images has been applied to internal imaging of PVA and two-part epoxy adhesives during cure, providing information on relative viscosity at different positions within the sample volume.

A Correlation Approach for Automatic Image Annotation
, 2006 The automatic annotation of images presents a particularly complex problem for machine learning researchers. In this work we experiment with semantic models and multi-class learning for the automatic annotation of query images.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Label-free single-particle imaging of the influenza virus by objective-type total internal reflection dark-field microscopy. [PDF]
PLoS ONE, 2012 Here we report label-free optical imaging of single particles of the influenza virus attached on a glass surface with a simple objective-type total internal reflection dark-field microscopy (TIRDFM).

Experimental verification of the limits of optical channel intensity reciprocity [PDF]
, 2012 Optical data links through the atmosphere suffer from turbulence-induced signal scintillation. In a coaxially-symmetric bidirectional link scenario, the variations of the axial intensities at both ends are correlated.

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Illumination waveform optimization for time-of-flight range imaging cameras [PDF]
, 2011 Time-of-flight range imaging sensors acquire an image of a scene, where in addition to standard intensity information, the range (or distance) is also measured concurrently by each pixel.
