NTSC composite color video is currently one of the most common formats of video broadcasting. Although the signal is analog, it can be decoded almost entirely digitally. Analog decoders offer limited video quality and require adjustments. Using digital techniques to implement NTSC decoding offers minimum adjustments and excellent video quality. This project presents the building blocks of digit...

In printing the final color image reproduction quality depends on the quality of the digital image as well as the properties of the printing system and the paper used. Although it is well known that the paper has a large influence on the print result it is seldom specified according to image quality attributes. Computer screens, digital cameras and printers are all technically specified with re...

In this paper, we propose a new method for enhancing the quality of direct volume rendered images. Unlike the typical image enhancement techniques which perform transformations in the image domain, we take the volume data into account and enhance the presentation of the volume in the rendered image by adjusting the rendering parameters. Our objective is not only to deliver a pleasing image with...

Multiple biological processes can generate sexual selection on male visual signals such as color. For example, females may prefer colorful males because those males are more readily detected (perceptual bias), or because male color conveys information about male quality and associated direct or indirect benefits to females. For example, male threespine stickleback often exhibit red throat color...

Evaluation of perceived image quality in color prints is a complex task, due to its subjectivity and dimensionality. Perceived image quality is influenced by a number of quality attributes. Evaluation of all attributes influence, and their influence on other attributes, is is a difficult and complex task. Because of this the most important attributes should be identified in order to achieve a m...

sodium bentonite can bind to dietary pigment and decreases yolk color scale. sodium bentonite is one of the main parts of formycine® gold, the effect of different levels of formycine® gold and dietary pigment on egg quality, egg yolk color and performance criteria of laying hens from 26 to 34 week of age were studied. one hundred ninety two hy-line hens were divided into 24 groups of 8 birds ea...

After fullerene and nanotubes, graphene is a new allotrope of carbon. This attractive nanomaterial can be produced by different methods. In this work, <span style="font-size: 11pt; color: #000000; font...

Multi-view video is a new video application requiring efficient coding algorithm to compress the huge data, while the color variations among different viewpoints deteriorate the visual quality of multiview video. This paper deals with these two problems simultaneously focusing on color. With the spatial block-matching information from multi-view video coding, color annotated images can be produ...

The preferences of children and adults were compared with respect to each of the following color image quality attributes: image brightness, saturation, sharpness, color balance (+M/+G), hue rotation, and contrast. It was found that the children had no strong preferences for sharpness or contrast. There was no statistical evidence that they disagreed with adults as to the optimal level of brigh...
