A trainable image pattern classification system for detection of damaged soybean seeds
… seeds, and four classes of soybean seeds discolored by fungi were determined using a spectroradiometer. Knowledge of the optical properties of soybean seeds provided a means of identifying that differences in spectral reflectance existed which could be used for discriminating among …

Multi-channel coded-aperture photography
… consists of inserting a set of patterned color filters into the aperture of the camera lens. This work generalizes the previous research on a single-channel coded aperture, by deploying distinct filters in the three primary color channels, in order to cope better with the effect of a Bayer …

Spectrum management for high efficiency photonic devices
… losses in optical intensity due to employed color filters and low ambient contrast ratio because of reflection of external light from the front surface. A luminescent film having quantum dots was placed inside an enclosed microcavity. The design for a high-contrast and high efficiency display …

Denoising and Demosaicking of Color Images
Most digital cameras capture images through Color Filter Arrays (CFA), and reconstruct the full color image from the CFA image. Each CFA pixel only captures one primary color component at each pixel location; the other primary components will be estimated using information from neighboring pixels. …

Advanced light manipulation and waveguiding in plasmonic nanostructured optical fibers.
… I demonstrated in-fiber polarization-dependent color filters by nanopatterning asymmetric metallic metasurface array on the end-facet of polarization-dependent photonic-crystal fibers. The asymmetric cross-typed nanoslit metasurface arrays are fabricated on the core of the optical fiber using a …

High quality optical and optoelectronic materials for efficient light management and solar spectrum control and conversion
… for an emissive cavity to replace absorptive color filters in a liquid crystal display (LCD). Strategies from LSCs are exploited to design the emissive component, quantum dots embedded in a polymer waveguide. The quantum dots used here have high quantum yields and narrow bandwidths, which are …
