Background and Objectives: Solvents are widely used in industries. Occupational exposure to organic solvents can lead to dysfunction of the nervous system. Since color-vision impairment can be a sensitive and early marker of neurotoxic damage, this study was designed to determine the influence of chronic occupational exposure to organic solvent mixtures on color vision. Materials and Methods: ...

An effective method for removal impulse noise in corrupted color images is proposed. The method consists of two steps. Outliers are first detected using spatial relationships between the color image components. Then the detected noise pixels are replaced with the output of the vector median filter over a local spatially connected area excluding the outliers, while noise-free pixels are left una...

Color space transformations are frequently used in image processing, graphics, and visualization applications. In many cases, these transformations are complex nonlinear functions, which prohibits their use in time-critical applications. In this paper, we present a new approach called Minimax Approximations for Color-space Transformations (MACT). We demonstrate MACT on three commonly used color...

K – medoids clustering is used as a tool for clustering color space based on the distance criterion. This paper presents a color image segmentation method which divides colour space into clusters. Through this paper, using various colour images, we will try to prove that K – Medoids converges to approximate the optimal solution based on this criteria theoretically as well as experimentally. Her...

In this paper, we propose a demosaicing algorithm which interpolates the missing pixels on the estimated edge direction with modified edge indicator. We use gradients to estimate the edge direction which considers cross-channel correlation in addition to the within-channel correlation. After the edge direction is estimated, we interpolate the missing color values more precisely in aid of weight...

Color is one of the most important visual variables in information visualization. In many cases, two-dimensional information can be color-coded based on a 2D color map. A variety of color maps as well as a number of quality criteria for the use of color have been presented. The choice of the best color map depends on the analytical task users intend to perform and the design space in choosing a...

A report summarizing the results of an international workshop on determination of color of streptomycetes is presented. The results suggest that the color systems which seem most practically appealing and effective to specialists on actinomycetes are those embracing a limited number of color names and groups. The broad groupings allow placement of isolates into reasonably well-defined categorie...

The enormous number of segment label in color image segmentation causes MRF-based color segmentation algorithm to suffer from complexity and storage explosion. To cope with this problem, this paper proposed a local belief aggregation (LBA) algorithm which restricts the number of messages to be aggregated from a neighboring node. The LBA is applied to our MRF model, which is formulated based on ...

acquired color deficiency in the tritan axis in parkinson’s disease has already been reported, manifesting itself as impaired performance in various visual tasks. however, its clinical significance has always been controversial. in this study we evaluated the performance of parkinson s disease patients in lanthony 15-desaturated clinical test and for the first time, compared it with the standar...
