Observer preferences in the color reproduction of pictorial images have been a topic of debate for many years. Through a series of psychophysical experiments we are trying to better understand the differences and trends in observer preferences for pictorial images, determine if cultural biases on preference exist, and finally generate a set of preferred color reproduced images for future experi...

Fermentation process plays an important role in tea manufacturing which is responsible for deciding the final quality of tea. But, during fermentation, it is always not possible to check the tea grains quality in uniform manner because of heavy lot of material. Also human access to the process is not advisable as the whole lot of material can not be tested with uniformity. Color and size appear...

A new algorithm of automatic white balance for electronic images has been developed. This algorithm uses hzzy logic rules for determinationi of the color parameters in order to minimize the color temperature difference of various light sources. This algorithm has been implemented in a newly designed electronic still camera, and resulted in highly improved image quality.

The overall image quality benefits substantially from good reproduction of black tones. Modern displays feature relatively low black level, making them capable rendering good dark tones. However, it is not clear if the black level of those displays is sufficient to produce a “absolute black” color, which appears no brighter than an arbitrary dark surface. To find the luminance necessary to invo...

During the transition period from narrowband to wideband speech transmission services, Artificial Bandwidth Extension (ABE) algorithms are able to reduce the perceptual degradation of narrowband-transmitted speech signals by extending the audio bandwidth. In this paper, we analyze whether the resulting speech quality can be predicted reliably with instrumental models. Estimations from the new I...

The illuminant estimation has an important role in many domain applications such as digital still cameras and mobile phones, where the final image quality could be heavily affected by a poor compensation of the ambient illumination effects. In this paper we present an algorithm, not dependent on the acquiring device, for illuminant estimation and compensation directly in the color filter array ...

This paper contributes to the limited research on roles ICT can play in impression-management strategies and is based on case studies done in the Swedish Police. It also gives a theoretical contribution by adopting a holistic approach to explain how ICT can contribute to giving a misleading picture of conditions. Output generated by ICT has nowadays a central role in follow-up activities and de...

The Joint Polar Satellite System (JPSS) launched the Suomi National Polar-Orbiting Partnership (NPP) satellite including the Visible Infrared Imager Radiometer Suite (VIIRS) on October 28, 2011which has the capability to monitor ocean color properties. Four months after launch, we present an initial assessment of the VIIRS ocean color products including inter-comparisons with satellite and in s...

difference in color is a major source of distinction between the lubricants extracted directly from the lubecuts and those manufactured in the reclaim units.the mentioned difference can be regarded as one of the main problesm for these products.in order to imporve the color quality of final product, possible modifications  in the reclamation method have been investigated. th effort has been des...

Color Space Analysis for Iris Recognition by Matthew K. Monaco Master of Science in Electrical Engineering West Virginia University Arun A. Ross, Ph.D., Chair This thesis investigates issues related to the processing of multispectral and color infrared images of the iris. When utilizing the color bands of the electromagnetic spectrum, the eye color and the components of texture (luminosity and ...
