Extraordinary Optical Transmission Plasmonic Color Filters (EOT-PCFs) with nanostructures have the advantages of consistent color, small size, and excellent color reproduction, making them a suitable replacement for colorant-based filters. Currently, gamut created by plasmonic filters is limited to standard red, green, blue (sRGB) space, which limits their use in future. To address this limitat...

An ultrathin angle-insensitive color filter enabling high saturation and a wide gamut is proposed by relying on magnesium hydride-hydrogenated amorphous silicon (MgH2-a-Si:H) lossy dielectric layer. Based effective medium theory, the MgH2-a-Si:H layer with an thickness can be equivalent to quasi-homogeneous complex refractive index, which tuned altering of MgH2 obtain targeted value imaginary p...

In this paper, a denoising approach, which exploits patchredundancy for removing Gaussian noise from RGB color images is described. Both geometrical and photometrical similarity of image patches have to be considered for learning the parameters of this Patch-based Locally Optimal Weiner(PLOW) filer. K-means clustering,with LARK(Locally Adaptive Regression Kernel) features, is used to identify t...

A procedure for the definition of optimum spectral transmission curves for any solid-state (especially silicon-based CCD) color camera is presented. The design of the target curves is based on computer simulation of the camera system and on the use of test colors with known spectral reflectances. Color errors are measured in a uniform color space (CIELUV) and by application of the Commission In...
