food quality, marketability, soluble solids, size and color of nectarine fruit is affected by the intensity and amount of direct sunlight. usually the outer areas of fruit trees get enough light and take the appropriate color. however, in the middle and lower part of trees, due to low light intensity, fruits have no good color and taste and their marketability were not desirable. to improve the...

Multimedia technology has been widely used in the delivery of instructional material, but previous studies have indicated that individual differences, especially cognitive styles, have significant effects on users’ preferences with respect to presentation of multimedia content. However, such research has thus far neglected to examine the effect of cognitive styles on users’ subjective perceptio...

Good print quality is the result of achieving high quality for a large number of attributes including color (color gamut and reproduction accuracy), density, tonal quality (tone reproduction and details in highlight, shadow and mid-tone), gloss, line quality (width, blurriness, raggedness,), text quality, adjacency (e.g. inter-color bleed), micro-uniformity (graininess), macro-uniformity (mottl...

The quality of the RGB color image degrades from the minute it is captured to the time it is displayed to the human observer. The image is subject to many kinds of distortions during the stages that it might pass through such as storing, processing, compressing, and transmitting, thus enhancing the image quality is a major important issue. This paper will introduce the effects of salt&pepper an...

In this paper we investigate the comparison of image quality assessment (IQA) methods for color images. An IQA evaluates a pair of images and returns a single number as a prediction of the perceived image difference. We introduce the Redundant Information Content Evaluation (RICE) that detects redundancies between distinct IQAs. Such comparisons help to develop or improve IQAs with respect to t...

This paper presents the results of a study which investigated the impact of cognitive styles on perceptual multimedia quality. More specifically, we examine the different preferences demonstrated by verbalizers and imagers when viewing multimedia content presented with different Quality of Service (QoS) levels pertaining to frame rates and color depth. Recognizing multimedia’s infotainment dual...

Environmental inequality is the suggestion that the working class, the poor, persons of color, and ultimately the economically disadvantaged are subjected to living conditions that may prove to be hazardous both personally, professionally, and also to the infrastructure of the urban communities that these people inhabit. These injustices affect not only housing but education, quality healthcare...

This paper proposed a detection method of rice process quality using the color and BP neural network. A rice process quality detection device based on computer vision technology was designed to get rice image, a circle of the radius R in the abdomen of the rice was determined as a color feature extraction area, and which was divided into five concentric sub-domains by the average area, the aver...

Although color is commonly experienced as an indispensable quality in describing the world around us, state-of-the art local featurebased representations are mostly based on shape description, and ignore color information. The description of color is hampered by the large amount of variations which causes the measured color values to vary significantly. In this paper we aim to extend the descri...
