In this paper, we study a color reproduction method to match the appearance of skin color images on CRT with a hardcopy under various viewing illuminants. Three color appearance models, von Kries, Fairchild and CIELAB, were applied to predict color reproduction on CRT display. Optimum color appearance model to predict color reproduction was estimated by psychophysical experiments based on the m...

Skin Color segmentation plays an important role in various applications such as face recognition, gesture recognition, human computer interaction etc. Face recognition is of main concern in skin color segmentation. There are various color models used for skin color segmentation (YCbCr, HSV and CIELAB) but appropriate method should be used for skin color segmentation. In real time the main probl...

In real world, body orientation is a problem of person identification. The variation of orientation makes features hard to be extracted in a uniform form. If the orientation is estimated, we can select suitable features based on orientation. It may improve the performance of person identification. For the reason, we propose a body orientation estimation method in this paper. First, body region ...

The fruit of Schisandra chinensis Turcz. (Baill.), namely "Wuweizi" in China, is a well-known herbal medicine and health food. At present, research focused on the extraction of effective chemical component and function identification. Little known about the secondary metabolism gene pathway of chemical composition. Its fruit color usually red, however, the white fruit color variation has been f...

This paper presents a novel design of face tracking algorithm and visual state estimation for a mobile robot face tracking interaction control system. The advantage of this design is that it can track a user’s face under several external uncertainties and estimate the system state without the knowledge about target’s 3D motion-model information. This feature is helpful for the development of a ...

OBJECTIVE To prove that the difference in human skin color can be used as a new fingerprint. METHODS A cross-sectional descriptive study was conducted in the Faculty of Medicine, The National Ribat University, Khartoum, Sudan between January and June 2010. The study consists of 139 subjects, which includes 41 Sudanese identical twins (82 subjects), 50 subjects from the general population, and...

An algorithm for segmenting skin regions in color images using color and edge information is presented. Skin colored regions are first detected using a Bayesian model of the human skin color. These regions are further segmented into skin region candidates that satisfy the homogeneity property of the human skin. We show that Bayesian skin color model outperforms many other models such as the pie...

The analysis of skin color with makeup is needed to examine the effect of makeup to human skin. Foundation is cosmetics to cover undesirable color on skin and gives basic color to skin. It is important evaluate a change of skin color by the foundation. The present paper modeled the optics of skin with foundation makeup by two layers. Then, the surface spectrum of skin with foundation makeup is ...

BACKGROUND This paper aims to compare the classification of race/skin color based on the discrete categories used by the Demographic Census of the Brazilian Institute of Geography and Statistics (IBGE) and a skin color scale with values ranging from 1 (lighter skin) to 10 (darker skin), examining whether choosing one alternative or the other can influence measures of self-evaluation of health s...

We introduce a multimodal facial color imaging modality that provides a conventional color image, parallel and cross-polarization color images, and a fluorescent color image. We characterize the imaging modality and describe the image analysis methods for objective evaluation of skin lesions. The parallel and cross-polarization color images are useful for the analysis of skin texture, pigmentat...
