In order to develop a computer‐based color consultation system, a quantitative evaluation of color harmony for interior images is constructed by using a linguistic‐based image scale. Conventionally, color harmony from any engineering perspective has received limited attention, because its successful evaluation requires the development of pleasure‐related features. In this study, a new pleasure‐related function of color linguistic distribution (CLD) is proposed to quantitatively represent the mental color impression of interior images upon a designed one‐dimensional linguistic‐based image scale of EXCITING‐CALM. Supported by a database that includes fashion trends, the distribution state of CLD is capable of indicating the fashion trends in Taiwan. Also, on the image scale, the grade of color harmony can be measured by its CLD similarity to a reference harmony distribution (RHD). Evaluated results demonstrate that interior design is primarily dominated by (low) saturation and (high) brightness. Also, results based on CIE1976 L*a*b* and CIE1976 L*u*v* color spaces are observed to be better than those based on the hue‐dominated method of Moon‐Spencer theory in corresponding with human's linguistic similarity, questionnaire‐based harmony evaluation, and social trends. Moreover, our solution percentage has been investigated as 72.3%, which is better than those of the Moon‐Spencer theory and of the “Law of Inverse Ratios of Areas.” For application purposes, the proposed system is suitable to analyze the mental impression of products from the perspective of the customer. © 1996 John Wiley & Sons, Inc.

A performance evaluation of color models between softcopy and hardcopy images was constructed closely following the CIE Technical Committee 1–27 guidelines. Conventionally, color models' performances were frequently evaluated under simplified environments, e.g., equally low luminance levels and dark surround. In this study, in the consideration of unequal luminance levels and dim surround, the two techniques of memory matching and paired comparison were used to assess the color similarity of two paired softcopies reproduced by four color models (i.e., von Kries, CIELAB, RLAB, and Hunt) against an original hardcopy image. Evaluated results based on the rank order of the Z scale values of thirty ordinary observers demonstrated that, on average, the Hunt model achieved the best color prediction against the worst one of the RLAB model. In addition, the aspects of screen uniformity, observer precision, and image and model dependencies were considered. © 1998 John Wiley & Sons, Inc. Col Res Appl, 23, 169–177, 1998

Synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome was first described as chronic recurrent multifocal osteomyelitis. Because of its rarity, a thorough description of its clinical manifestations is lacking. Herein, we describe the clinical manifestations and imaging features, especially the enthesopathy in bilateral Achilles tendons, of a middle-aged Asian woman with SAPHO syndrome, who improved after diclofenac treatment.
