GRAY COMPONENT REPLACEMENT: A Practical Approach
نویسنده
چکیده
Introduction The transformation of a digital image from a three-dimensional color space, such as RGB, XYZ, L*u*v*, etc., to four-dimensional colorant space (typically cyan, magenta, yellow, and black) is in general underdetermined. (The reasons for the addition of a black colorant are detailed in Yule. [1]) We therefore have a degree of freedom for colors within the three-colorant gamut; without loss of generality we may use this degree of freedom to fix the level of black.

Detecting spatially varying gray component replacement with application in watermarking printed images
We present a method to include watermarks in printed images. Under specific viewing conditions and accurate printer calibration, the same color printed using different gray component replacement strategies (GCR) will look the same. We spatially vary the GCR along the image in a manner that is not perceptible, and we employ an estimation method to detect such changes. The choice of GCR for a giv...
متن کاملSpatially Varying Gray Component Replacement To Watermark Printed Images
We present a method to include watermarks in printed images. It does not degrade textures and has a high information channel capacity. With accurate printer calibration, in theory, the same color under different gray component replacement strategies (GCR) should look the same, under specific viewing conditions. We spatially vary the GCR along the image in a manner that is not perceptible, and w...
متن کاملCondition Based Maintenance for Two-Component Systems with Reliability and Cost Considerations
This paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. The failure of each component results in the failure of the system. The components are inspected periodically and their deterioration degrees are monitored. The components can be maintained using different maintenance actions (repair...
متن کاملApplying an integrated fuzzy gray MCDM approach: A case study on mineral processing plant site selection
The accurate selection of a processing plant site can result in decreasing total mining cost. This problem can be solved by multi-criteria decision-making (MCDM) methods. This research introduces a new approach by integrating fuzzy AHP and gray MCDM methods to solve all decision-making problems. The approach is applied in the case of a copper mine area. The critical criteria are considered adja...
متن کاملDetermination of the Effect of Gray Component Replacement Level on Colorimetric Characteristics of Color Proof
The main goal of this study is determination the effect of GCR (gray component replacement) levels on colorimetric characteristics of color proof. To determine the effect of GCR levels on colors of color proofs, a comparison of 2D and 3D color gamuts depending on GCR level have been performed. In addition to obtain better assessment of the effect of GCR levels on color gamut were calculate volu...
