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...

BACKGROUND Skin color is a well-recognized adaptive trait and has been studied extensively in humans. Understanding the genetic basis of adaptation of skin color in various populations has many implications in human evolution and medicine. DISCUSSION Impressive progress has been made recently to identify genes associated with skin color variation in a wide range of geographical and temporal p...

The skin color signal is the product of skin reflectances and spectral power distribution of illuminants. In this paper we use principal component analysis to obtain basis functions for an ensemble of skin color signals and test the reconstruction goodness with different number of basis functions and types of normalization. We demonstrate the usefulness of the basis functions in two application...

Real time faces detection and face tracking is one of the challenging problems in application like computer human interaction, video surveillance, biometrics etc. In this paper we are presenting an algorithm for real time face detection and tracking using skin color segmentation and region properties. First segmentation of skin regions from an image is done by using different color models. Skin...

My article, Profiling the New Immigrant Worker: The Effects of Skin Color and Height, presents strong evidence that darker skin color is associated with lower wages for new legal immigrants to the United States. Taking into account education, English language proficiency, occupation in the source country, and family background, as well as Hispanic ethnicity, race, and country of birth, I found ...

BACKGROUND Dental restoration or prosthesis in harmony with adjacent natural teeth color is indispensable part for the successful esthetic outcome. The studies indicate is existence of correlation between teeth and skin color. Teeth and skin color are changed over the aging process. The aim of the study was to explore the role of age on the tooth and skin color parameters, and to investigate th...

This paper presents a color segmentation method based on RCE neural network for hand image segmentation in the gesture-based human–service robot interaction system. The study on skin color distributions in different color spaces indicates that skin colors cluster in a small region in a color space. The RCE neural network characterizes the skin color distribution region using skin color prototyp...

The colors of the human skin represent a special category of colors, because they are distinctive from the colors of other natural objects. This category is found as a cluster in color spaces, and the skin color variations between people are mostly due to differences in the intensity. Besides, the face detection based on skin color detection is a faster method as compared to other techniques. I...
