Due to the increasing popularity and affordability of color imaging devices, color characterization for these devices becomes an important subject. In other words, a set of color profile(s) needs to be generated for each device to transform the device dependent color space to a device independent one. This paper will concentrate on color characterization of scanners. Up to now, most scanner cha...

Color plays an important role in human visual attention. Therefore, high color contrasts are often used for warning or information purposes (e.g. traffic signs, warning signs in industrial areas). In this work the color contrasts are evaluated in a perceptually uniform color space to achieve a human-like color classification. The results of the color analysis are organized in several feature ma...

Video-based face recognition has attracted significant attention in many applications such as media technology, network security, human-machine interfaces, and automatic access control system in the past decade. The usual way for face recognition is based upon the grayscale image produced by combining the three color component images. In this work, we consider grayscale image as well as color s...

with the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. tracking people as they move through a camera network with non-overlapping field...

A color correction method for balancing the color appearances, among a group of images, about a specified object or scene, such as panoramic images and object movies, is developed and tested in this paper. In order to increase the running speed of color correction and reduce the out-of-gamut color pixels, we introduce the selection of principal regions. The average color values of principal reg...

It is concluded from presented experimental and theoretical consideration that the notion of “light source” is inadequate for description of the color perception and an alternative way to define and to describe the illumination is suggested. Color constancy as phenomena of perceiving the same color of curved and homogeneously painted surfaces is considered and it is shown that surface colors ca...

Color naming, which relates colors with color names, can help people with a semantic analysis of images in many computer vision applications. In this paper, we propose a novel salient color names based color descriptor (SCNCD) to describe colors. SCNCD utilizes salient color names to guarantee that a higher probability will be assigned to the color name which is nearer to the color. Based on SC...

In this paper, we propose an original approach in order to improve the results of color im-age segmentation by pixel classification. We define a new kind of color space by selecting a setof color components which can belong to any of the different classical color spaces. Suchspaces, which have neither psycho-visual nor physical color significance, are named hybridcolor space...

Color information of natural images can be considered as a highly correlated vector space. Many different color spaces have been proposed in the literature with different motivations toward modeling and analysis of this stochastic field. Recently, color transfer among different images has been under investigation. Color transferring consists of two major categories: colorizing grayscale images ...

The ability to restore perceived colors for the output of color imaging devices is of great interest. The quality of color reproduction depends on the accuracy of the color correction function used, on the recording and rendering illumination as well as on the spectral sensitivies of the color imaging device used. Much work has been done to develop and evaluate the quality of different color co...
