The first purpose of this thesis was to design and complete psychophysical experiments for scaling lightness and lightness differences for achromatic percepts above and below the lightness of diffuse white (L*=100). Below diffuse white experiments were conducted under reference conditions recommended by CIE for color difference research. Overall a range of CIELAB lightness values from 7 to 183 ...

Basidiocarps of species of Armillaria, Russula, Lactarius and  Agaricus with fungal infection were collected from different regions of Iran. Portions of infected carpophores, were taken and cultured on PDA, PCA and MEA. Fungicolous isolates were identified on the basis of morphological characters such as: color and shape of colony, morphology and branching of conidiophores, manner of proliferat...

In congenital color blindness the red-green discrimination is impaired resulting in an increased confusion between those colors with yellow. Our post-receptoral physiological mechanisms are organized in two pathways for color perception, a red-green (protanopic and deuteranopic) and a blue-yellow (tritanopic). We argue that the discrimination losses in the yellow area in congenital color vision...

This project seeks to reproduce the work of [Levin] on colorization of a black and white image. The approach used takes two black and white images, which are identical except for color markings on one of them. The colored result is based on an optimization problem that has two sets of constraints: First, the color of pixels should be close to their marked color, if applicable. Second, the color...

Color image acquisition and image processing have become a key in modern data applications. In order to provide high quality images, the field of accurate acquisition is most important in respect to all further processing steps. This is especially true for color correction and white balancing on color sensors. But a whole variety of current image sensors possess an incorrect color rendition due...

the purpose of this study was to investigate the brain activation patterns in response to thehuman color preference by using a functional magnetic resonance imaging (fmri). a total of 31 healthyhumans without color blindness were participated in this study. the brain activation was induced by viewingof eight different colors: black, gray, blue, green, earthy yellow, red, yellow and white. the q...

Previous work has shown that illiterate subjects are better at naming two-dimensional representations of real objects when presented as colored photos as compared to black and white drawings. This raises the question if color or textural details selectively improve object recognition and naming in illiterate compared to literate subjects. In this study, we investigated whether the surface textu...

The authors investigated the effects of a brief video intervention on the racial attitudes of White university students. One hundred thirty-eight self-identified White students were randomly assigned to either an experimental condition in which they viewed a video documenting the pervasiveness of institutional racism and White privilege in the United States or a neutral control condition. Findi...

In this paper, we report white dwarfs identified in the 5th Data Release of Large Area Multi-Object fibre Spectroscopic Telescope, including spectral types DA, DB, DC, DZ, and so on. There are 2 625 DA spectra 281 stars, 182 DB 166 62 DC 58 36 DZ 33 stars many other identified, addition to our previous paper (Data 2). Among those sources, 393 46 new identifications after cross-matching with lit...
