Rationale of Color Quality Scale
The purpose of this article is to solicit comments from the solid state lighting (SSL) industry on the Color Quality Scale (CQS) developed by National Institute of Standards and Technology (NIST). The CQS is being discussed as one of the proposals in the International Commission on Illumination (CIE) Technical Committee (TC) 1-69 and final discussions are in progress in the TC toward selecting ...
متن کاملDevelopment of a Color Quality Scale
A Color Quality Scale (CQS) is being developed at NIST, which evaluates several aspects of the quality of the color of objects illuminated by a light source. This metric involves several facets of color quality, including color rendering, chromatic discrimination, and observer preferences. The method for calculating the CQS is derived from modifications to the method used in the CIE's Color Ren...
متن کاملTask-based Color Scale Design
Color is commonly used in data visualization in order to convey a wide variety of types of information: metric values, pattern, extrema, emphasis, and others. A distressingly large percentage of these visualizations appear to use the default color scale for the visualization package used to create them. While sometimes this is an appropriate choice, careful consideration of the implications of ...
متن کاملColor and Scale: The Spatial Structure of Color Images
For grey-value images, it is well accepted that the neighborhood rather than the pixel carries the geometrical interpretation. Interestingly the spatial configuration of the neighborhood is the basis for the perception of humans. Common practise in color image processing, is to use the color information without considering the spatial structure. We aim at a physical basis for the local interpre...
متن کاملColor 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.
