Edge Strength Filter Based Color Filter Array Interpolation
IEEE Transactions on Image Processing, 2012For economic reasons, most digital cameras use color filter arrays instead of beam splitters to capture image data. As a result of this, only one of the required three color samples becomes available at each pixel location and the other two need to be interpolated. This process is called Color Filter Array (CFA) interpolation or demosaicing.

Exploiting Color Strength to Improve Color Correction
2012 IEEE International Symposium on Multimedia, 2012Color information is an important feature for many vision algorithms including color correction, image retrieval and tracking. In this paper, we study the limitations of color measurement accuracy and explore how this information can be used to improve the performance of color correction.

The Effect of Light Color on Muscular Strength and Power
Perceptual and Motor Skills, 2008The purpose of this study was to assess the effect of the color of light in a room on muscular strength and power. A convenience sample of 18 men ( M age = 20.4 yr., SD = 1.2) performed a modified Wingate Anaerobic Cycle Test for muscular power and a hand grip strength test in each of the following conditions: red, blue, and white (neutral) ambient ...

Chromatic Strength of Colors: Dominant Wavelength and Purity
Journal of the Optical Society of America, 1967A new visual threshold lying between the colors that appear to contain gray and those that appear fluorescent has been determined as a function of dominant wavelength at high purity on a white (7000 K) background. The function is found to be an approximately constant multiple of the previously known purity threshold; it is independent of purity and ...

Effect of Viewed Color on Hand-Grip Strength
Perceptual and Motor Skills, 1998Published reports on the effects of viewed color on physical strength are compromised by failure to specify each of the three dimensions of the color stimuli used The present study investigated the relationship between color and grip strength by independently measuring the effects of the three dimensions of color.

Color image watermarking with adaptive strength of insertion
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004The paper presents a watermarking technique, specific to color images. The insertion and the detection are based on the 2D discrete wavelet transform, applied on each color component. Three color vectors are extracted from the wavelet coefficients. The insertion consists of modifying one vector for each location, with regard to the bit value and the ...

Color Strength and Colorfastness of Flax Fabrics Dyed with Natural Colorants
Clothing and Textiles Research Journal, 2003Flax fabrics were dyed with natural colorants extracted from animal and plant sources. The colorants used were cochineal, red sandalwood, madder root, and osage orange. The influence of the order of mordanting on color strength of dyed fabrics was analyzed. Colorfastness tests for washing, crocking, and perspiration were performed.

Color or Brightness Effects on Grip Strength?
Perceptual and Motor Skills, 1998Research into the effects of color on grip strength has produced inconsistent results, but studies show methodological problems, for example, the non-standardised reporting of stimulus colours, differing intertrial rests, and the neglect of warm-up effects. The present study was designed to replicate the 1989 work by Hasson, et al.

Chromatic Strengths of Colors, Part II The Munsell System
Journal of the Optical Society of America, 1968An approximate model of the Munsell color space in terms of dominant wavelength and colorimetric purity is described. This approximation space describes the Value and Chroma relations as functions of chromaticity and the Chroma relations as a function of colorimetric purity, but does not describe the Hue spacing. A single curve describes (approximately)

Affect Aroused by Color, a Function of Stimulus Strength
Journal of Projective Techniques and Personality Assessment, 1966Abstract The study investigated the effects of stimulus strength of color and degree of autism on the response to color, as it reflects an affective or cognitive process. Subjects were 30 male schizophrenics, 15 high autistic and 15 low autistic. Color was measured by selected cards from the HIT containing both high and low stimulus strength. Responses
