The Freundlich model was evaluated for use to assess the effect of heat on the adsorption capacity of an activated carbon for decolorizing/deodorizing corn zein. Because zein protein and its color/odor components are all adsorbed by activated carbon, a method to monitor their removal was needed. Yellow color is due to xanthophylls; a contributor to off-odor is diferuloylputrescine. The off-odor...

Traditionally, data hiding and compression have had contradictory goals. The former problem adds perceptually irrelevant information in order to embed data, while the latter removes this irrelevancy and redundancy to reduce storage requirements. In this paper, we use data hiding to help improve signal compression.We take an unconventional approach and consider “piggy-backing” the color informat...

In this paper we present a new alternative noise reduction method for color images that were corrupted with additive Gaussian noise. We illustrate that color images have to be processed in a different way than most of the state-of-the-art methods. The proposed method consists of two sub-filters. The main concern of the first subfilter is to distinguish between local variations due to noise and ...

The arousal theory of color proposes that red is associated with arousal. Research on the color-in-context theory, in turn, states that the context in which red is perceived influences its valence-related meaning and behavioral responses to it. This study faces and integrates these theories by examining the influence of red on both arousal and valence perceptions of test-relevant and neutral st...

Recent studies have shown correlations between perceived colors and aspects of a musical piece such as tonality, tempo and musical articulation. Other studies have demonstrated that major and minor tonalities of music trigger people to perceived a different hue of colors. The purpose of this study is to investigate the correlation between musical aspects and the attribution of colors and emotio...

In this paper, a real time face recognition for color image sequences is presented. The proposed algorithm applies three stages: a head region is estimated by the DCFR(Detection of Candidate for Face Regions) scheme in the first stage, the face region is searched inside the head region using the MCC(major color component) in the second stage and its faceness is tested by the TRFF (Topological R...

Text detection in color images has become an active research area in the past few decades. In this paper, we present a novel approach to accurately detect text in color images possibly with a complex background. The proposed algorithm is based on the combination of connected component and texture feature analysis of unknown text region contours. First, we utilize an elaborate color image edge d...

This paper proposes a content-based image retrieval method based on color histograms and the discrete cosine transform (DCT). Color histogram characterizes an image by its color distribution, but the drawback of a global histogram representation is that spatial information (such as object location, shape, and texture) is discarded. Thus the images retrieved by using the color histogram only may...

Grapheme-color synesthetes experience consistent, automatic and idiosyncratic colors associated with specific letters and numbers. Frequently, these specific associations exhibit achromatic synesthetic qualities (e.g. white, black or gray). In this study, we have investigated for the first time the neural basis of achromatic synesthesias, their relationship to chromatic synesthesias and the ach...

The parallel self-organizing neural network (PSONN) architecture uses bilevel sigmoidal activation functions for the purpose of extraction of embedded objects from pure color noisy perspectives. The process of extraction often involves an enhancement of the images under consideration. The network employs multilevel sigmoidal activation function to segment true color images. Both these activatio...
