    摘要： What is disclosed is a system and method for merit-based gamut mapping. In one embodiment, color points are clustered in regions of interest within a color space. Each cluster is associated with a gamut mapping function and a merit function. Mapping parameters of each gamut mapping function are iteratively varied to optimize the values based on the merit function value. An optimized gamut mapping function results. Optimized gamut mapping functions of adjacent clusters are blended together by blending the value of the gamut mapping function for a point of a cluster with a value produced by the gamut mapping function of an adjacent cluster for that color point. The composite gamut mapping function contains the optimized gamut mapping functions of all clusters is then output for use in mapping points within those clusters to points within the target gamut. The composite gamut mapping function exploits local advantages of each cluster.

    摘要： A method of color management for image marking devices utilizes an automated spot color editor having a control module accessing a graphical user interface. The method includes receiving image data input, in either device-dependent color space or device-independent color space, for a marking job. It is determined whether spot colors are present within the image data input and whether the CMYK values for each of the spot colors present within the image data input are included in the marking device spot color dictionary. Operational parameters for the automated spot color editor are initialized, with operational parameters including the desired performance criteria to be minimized by the automated spot color editor through selection of one or more matrices from a plurality of possible gain matrices to identify new CMYK values. The quality level of the new CMYK values is assessed and new CMYK values are transmitted to image printing device(s).

    摘要： A method for processing black point compensation parameters for a color image to be printed so as to enhance image quality of the color image is provided. The method includes analyzing image content of a received color image to identify one or more performance attributes to be considered during a black point compensation parameters processing procedure, the performance attributes estimate an effect of the black point compensation parameters on the image quality of the received color image; selecting, based on the identified performance attributes, a black point compensation (BPC) algorithm to be used during the processing procedure; deriving a model using the identified performance attribute that is configured to estimate relationships between the black point compensation parameters and the identified performance attribute; maximizing the performance attribute of the derived model so as to process the BPC parameters for the color image; and using the processed black point compensation parameters to construct output device profiles.

    摘要： A method and system for providing a feedback based dynamic pricing algorithm with an embedded controller for a HOT (High Occupancy Toll) lane. An input-output transfer function of a vehicle flow with respect to a HOT lane can be obtained utilizing a simulation module. A feedback controller combined with, for example, a Smith predictor can be designed to avoid an unstable behavior due to a time delay in the HOT lane, a price regulation, and a large transient caused by an integral part of the controller due to traffic jams. A driver behavior preference model can be derived based on a relationship between a toll rate and several characteristics of the HOT lane and a general purpose lane. The feedback controller and the behavior preference model can then be implemented to set the toll rate in real-time in order to satisfy a desired performance metric.

    摘要： Differences between an offline spectrophotometer and an inline spectrophotometer can result in differences between a hardcopy target color and a printed reproduction of that color. The inline spectrophotometer is inside of a printer and configured to measure printer output. As such, the inline spectrophotometer cannot conveniently measure the hardcopy target color. A printing error or an instrument offset can be determined and passed to a color correction module that updates the device dependent color specification associated with the given spot color. This color specification may be stored, for example, in the printer controller, and used when a document subsequently calls for that spot color, thereby providing accurate color reproduction from that particular printer incorporating that particular inline spectrophotometer.
