In a single-chip digital color imaging sensor, a color filter array (CFA) is used to obtain sampled spectral components (red, green and blue) in an interleaved fashion. Color demosaicing is the process of interpolating these regularly spaced sampled values into the dense pixel maps for each spectral components. In this paper we present techniques for interpolating the color images in the YUV co...

This paper introduces a computer cystem for color picyure processing and its principal features. First the hardware aspectB are explained, including the basic characteristics of I/O devices. The interactive feature of our system is singled out, and it is developed to a system concept called "Color Picture Analysis and Display System" The color analysis method and its software are presented and ...

This article applies the interpoint-distance model (IDM) to explain composite color categories that continue to challenge existing models in the literature. Using universal cognitive principles and heuristics suggested in the IDM, analyses demonstrate that the composite category blue-green (or GRUE) seen in many languages is one of several natural coding configurations expected in the developme...

Four experiments investigated Stroop interference using geometrically transformed words. Over experiments, reading was made increasingly difficult by manipulating orientation uncertainty and the number of noncolor words. As a consequence, time to read color words aloud increased dramatically. Yet, even when reading a color word was considerably slower than naming the color of ink in which the w...

This paper presents the concept of color space normalization (CSN) and two CSN techniques, i.e., the within-color-component normalization technique (CSN-I) and the across-color-component normalization technique (CSN-II), for enhancing the discriminating power of color spaces for face recognition. Different color spaces usually display different discriminating power, and our experiments on a lar...

This work aims to analyze the use of spatial information and the effectiveness of such information for tracking a person’s head in a video sequence. This thesis introduces new concepts that make use of color information along with a limited amount of spatial information on a global scale. Also, existing concepts like co-occurrence matrices are adapted to color images to provide a concept that u...

This paper presents a novel example-based stippling technique that employs a simple and intuitive concept to convert a color image into a pointillism painting. Our method relies on analyzing and imitating the color distributions of Seurat’s paintings to obtain a statistical color model. Then, this model can be easily combined with the modified multi-class blue noise sampling to stylize an input...

{ The use of mathematical morphology in low and mid-level image processing and computer vision applications has allowed the development of a class of techniques for analyzing shape information in monochrome images. In this paper these techniques are extended to color images. We investigate two approaches for \color morphology": a vector approach, in which color vectors are ranked using a multiv...

Modern digital still cameras sample the color spectrum using a color filter array coated to the CCD array such that each pixel samples only one color channel. The result is a mosaic of color samples which is used to reconstruct the full color image by taking the information of the pixels’ neighborhood. This process is called demosaicking. While standard literature evaluates the performance of t...

Delving into the close relationship between sense and emotion mingled with language can be of utmost importance in studies related to management of emotions. In this regard, the current study qualitatively attempted to examine to what extent sense-induced emotions can be recognized, labelled, and managed by individuals. To this end, 36 Iranian males and females were asked to participate in inte...
