A color-tunable novel-look-up-table (CT-NLUT) for fast one-step calculation of full-color computer-generated holograms is proposed. The proposed method is composed of four principal fringe patterns (PFPs) such as a baseline, a depth-compensating and two color-compensating PFPs. CGH patterns for one color are calculated by combined use of baseline-PFP and depth-compensating-PFP and from them, th...

We study generalizations of Demuth’s Theorem, which states that the image of a Martin-Löf random real under a tt-reduction is either computable or Turing equivalent to a Martin-Löf random real. We show that Demuth’s Theorem holds for Schnorr randomness and computable randomness (answering a question of Franklin), but that it cannot be strengthened by replacing the Turing equivalence in the stat...

application of atoxigenic strains of aspergillus flavus to reduce aflatoxin levels is the most successful strategy applied in some agricultural crops. the role of ammonium hydroxide for preliminary screening of the competitiveness of atoxigenic a. flavus isolates to interfere with aflatoxin production by highly toxigenic isolates were evaluated. out of 270 a. flavus isolates, 17 were detected a...

Given a color image that was quantized in some hidden color space (termed compression color space) during previous JPEG compression, we aim to estimate this unknown compression color space from the image. This knowledge is potentially useful for color image enhancement and JPEG re-compression. JPEG quantizes the discrete cosine transform (DCT) coefficients of each color plane independently duri...

Color space transformation (or color correction) needs to be performed in typical imaging devices because the spectral sensitivity functions of the sensors deviate from the desired target color space. Several researchers have shown that when the color channels are correlated, color correction can result in sensor noise amplification [1-4]. In this paper, we describe a color correction method th...

An in situ enzyme-linked immunosorbent assay (ELISA), performed directly on fixed varicella-zoster virus-infected monolayers, was used to quantitate viral antigen, and by color reduction it was used to evaluate the activity of drugs against varicella-zoster virus. Color production in the ELISA (optical density) was directly related to the dose of input virus. Antigen representing 5 to 10 plaque...

A k-edge-coloring of a graph G = (V, E) is a function c that assigns an integer c(e) (called color) in {0, 1, · · · , k−1} to every edge e ∈ E so that adjacent edges get different colors. A k-edge-coloring is linear compact if the colors incident to every vertex are consecutive. The problem k − LCCP is to determine whether a given graph admits a linear compact k-edge coloring. A k-edge-coloring...
