Color Moving Pictures Quality Metric
This paper presents a comprehensive quality metric for color moving pictures which is based on a spatio-temporal vision model and on the opponent-colors theory. The metric is used to assess the quality of MPEG compressed video streams and is compared with a grayscale video quality metric developed recently.
متن کاملDigital Color Restoration of Faded Motion Pictures
The cinematographic documents recorded on chemical support represent a significant cultural heritage. These films, however, are often very damaged. Using powerful multimedia platforms, motion pictures can be digitized at a high resolution, processed and reproduced, thus allowing a digital restoration of old films. We present in this paper a technique to restore faded color films. This method co...

Studies show that all the published work in flicker correction to date only deals with black and white motion pictures. In this paper, we will look into the problem of flicker correction in color motion pictures and propose a method to address this problem. The method is based on a simplified flicker parameter model developed by us in [5] which was originally used for flicker correction in blac...

This talk will discuss common sources of light, the...
متن کاملThree-dimensional pictures of molecular models--lysozyme.
The first three-dimensional pictures of molecular models using the full color Xograph@ technique suggest the value of such illustrations for conveying spatial impressions on the printed page without the use of auxiliary devices. Pictures of a space-filling model of lysozyme and its substrate, accompanied by discussiod of the mechanism of action in terms of active sites, are presented as an exam...
