چکیده

A new CIE color appearance model (CIECAM02) has been developed. This paper describes the three major drawbacks of the earlier CIECAM97s model, and shows how the new model performs in these color regions. In addition, both models were tested using available data groups. The results are consistent in that CIECAM02 performed as well as, or better than, CIECAM97s in almost all cases, there being a large improvement in the prediction of saturation. The CIECAM02 model can therefore be considered as a possible replacement for CIECAM97s for all image applications.

Unique Hue Data for Colour Appearance Models. Part III: Comparison with NCS Unique Hues

In this study, Swedish Natural Color System (NCS) unique hue data were used to evaluate the performance of unique hue predictions by the CIECAM02 colour appearance model. The colour appearance of 108 NCS unique hue stimuli was predicted using CIECAM02, and their distributions were represented in a CIECAM02 ac–bc chromatic diagram. The best-fitting line for each of the four unique hues was found...

ICC Color Management and CIECAM02

The International Color Consortium (ICC) has developed and refined a comprehensive and rigorous system for managing color. The CIE technical committee 8-01 has proposed a color appearance model for imaging applications. This paper describes issues that have to be considered when the CIECAM02 color appearance model is used within the framework of the ICC color management system. They concern dec...

Scaling perceived saturation.

Two psychophysical experiments were conducted at North Carolina State University (NCSU) and Rochester Institute of Technology (RIT) to obtain replicated perceived saturation data from color normal observers on the order of one unit of saturation. The same 37 Munsell sample sheets, including up to four references that had similar perceived saturation but different hue, were used in both experime...

Development of a perceptual colorimeter based on a conventional CCD camera with more than three color channels

In order to improve the precision of colorimeters based on a digital image capture device, we increased the number of acquisition channels by using a supplementary filter placed in front of the color camera and taking two images of the scene: one without the filter (3 RGB channels) and one with the filter (3 different UVW channels). We selected a wide-band cyan filter that increases the transmi...

The CIECAM02 Color Appearance Model

The CIE Technical Committee 8-01, color appearance models for color management applications, has recently proposed a single set of revisions to the CIECAM97s color appearance model. This new model, called CIECAM02, is based on CIECAM97s but includes many revisions and some simplifications. A partial list of revisions includes a linear chromatic adaptation transform, a new non-linear response co...
