Snapshot multispectral endomicroscopy
Optics Letters, 2020Multispectral endomicroscopy provides tissue functional information in addition to structural information for accurate disease diagnosis. In this Letter, we propose a snapshot multispectral endomicroscope that employs a fiber bundle to deliver an in-body tissue spatial–spectral datastream to an external compressive spectral imager. Equipped with an end-

The Multispectral Dermoscope has been used for imaging skin lesions. Illumination at three different spectral regions and subsequent image processing can provide information on the localization of melanin, hemoglobin and scattering structures in the skin.

Applied Optics, 2011
Large-aperture linear diffractive axicons are optical devices providing achromatic nondiffracting beams with an extended depth of focus when illuminated by white light sources. Annular apertures introduce chromatic foci separation, making chromatic imaging possible despite important radiometric losses.

Interpretation, 2018
Seismic coherence is a routine measure of seismic reflection similarity for interpreters seeking structural boundary and discontinuity features that may be not properly highlighted on original amplitude volumes. One mostly wishes to use the broadest band seismic data for interpretation.

Multispectral Bilateral Video Fusion
IEEE Transactions on Image Processing, 2007We present a technique for enhancing underexposed visible-spectrum video by fusing it with simultaneously captured video from sensors in nonvisible spectra, such as Short Wave IR or Near IR. Although IR sensors can accurately capture video in low-light and night-vision applications, they lack the color and relative luminances of visible-spectrum ...

Multispectral processing without spectra
Journal of the Optical Society of America A, 2003It is often the case that multiplications of whole spectra, component by component, must be carried out,for example when light reflects from or is transmitted through materials. This leads to particularly taxing calculations, especially in spectrally based ray tracing or radiosity in graphics, making a full-spectrum method prohibitively expensive ...

PCA-Based Multispectral Band Compression and Multispectral Palmprint Recognition
2011 International Conference on Hand-Based Biometrics, 2011In this paper, we propose a PCA-based spectral band compression and multispectral palmprint recognition method. This method first exploits PCA to compress original multispectral bands to a smaller number of 'bands' and then uses the compressed bands to classify palmprint images.

Multispectral Satellite Image Processing
2016Having begun in the 1970s with the American Landsat program, the use of optical satellite images for civilian purposes has since experienced significant technological advancements. In the space of 10 years, the images provided by Earth observation satellites have gone from high to very high spatial resolution, from a decametric resolution to a ...
