A measure for the color reproduction ability of a color imaging device is important for comparison purposes as well as for the sensor design process. Several figures of merit which describe this ability in a single measure have been proposed in the past. All these measures have shortcomings in that their error measure is defined in a non-representative color space for human color perception, or...

This paper examines color from multiple perspectives. A theory is proposed that the current color spaces are poorly designed for video quality and video coding purposes. The implication is that objective video quality metrics could be improved by the development of a field-specific color edge detection algorithm or color distance measurement. A prototype subjective database is provided that cou...

Experiential and sensory evaluation is an ancient method that remains important in the current quality control system of Traditional Chinese Medicines (TCMs). The process is rapid and convenient when evaluating the quality of crude materials in TCM markets. However, sensory evaluation has been met with skepticism because it is mainly based on experience and lacks a scientific basis. In this stu...

Halftoning, the transformation from a con-tone image to a binary one, is a very important part of the printing process. The print quality is very much dependent on the characteristics of the halftoning method that was used. Finding one objective halftone image quality measure that covers all the aspects of quality is a very difficult, if not impossible, task. One of the reasons is simply the fa...

Naturally existing colored cotton was far from perfection due to having genetic factors for lower yield, poor fiber quality and monotonous color. These factors posed a challenge to colored cotton breeding and innovation. To identify novel quantitative trait loci (QTL) for fiber color along with understanding of correlation between fiber color and quality in colored cotton, a RIL and two F2 popu...

Color image quality depends on many factors, such as the initial capture system and its color image processing, compression, transmission, the output device, media and associated viewing conditions. In this paper, we are primarily concerned with color image quality in relation to compression and transmission. We review the typical visual artifacts that occur due to high compression ratios and/o...

this study determined optimum conditions for drying pomegranate arils in a solar dryer. a cabinet solar dryer was used in active and mixed modes. the response surface method was employed with nine treatments (runs) and a control run (3 m/s air velocity and 2 cm in thickness) and five replications. the bryte cultivar was tested and samples were dried to approximately 10% moisture. drying time, v...

An experiment was conducted to develop a plant extracts based quality indicator for monitoring aerobically packed chicken meat quality during storage at room temperature (25±1oC) until spoiled. Ripen black mulberry (Morus nigra) fruit extracts containing anthocyanins was used for developing quality indicator. Filter paper based indicator was exposed to the closed fresh meat environment. Changes...
