BACKGROUND Skin pigmentation is a key factor for ultraviolet radiation exposure-related cancers and can make a significant contribution to the patterns of other diseases. For surveys, and to appropriately target cancer control activities, valid and reliable measures of skin color are required. METHODS Validity and reliability of the Munsell Soil Color Charts were investigated for skin color a...

In this paper we present a skin color model for accurate face detection which combines skin color learning and image segmentation. This approach starts from a coarse segmentation which provides regions of homogeneous statistical color distribution. Some regions represent parts of human skin and are selected by minimizing an error between the color distribution of each region and the output of a...

A lot of computer vision applications benefit from robust skin color classification. But this is a hard challenge due to the various image conditions like camera settings, illumination, light source, shadows and many more. Furthermore people’s tans and ethnic groups also extend those conditions. In this work we present a parametric skin color classifier that can be adapted to the conditions of ...

This paper presents a method for analyzing the variations of the RGB spectrum of lesion skin images using the novel segmentation process based on Six Sigma concept. This analysis further contemplates on the incidence and propagation of cancer. It is based on the underlying principles of Dr. W.A. Shewhart’s Control Charts, which focuses on the fact that the variability does exist in all repetiti...

This paper proposes an automatic image correction method for portrait photographs, which promotes consistency of facial skin color by suppressing changes due to background colors. In is often distorted the lighting environment (e.g., light reflected from a colored wall and over-exposure camera strobe). distortion emphasized when artificially synthesized with another color, appearance becomes un...

Abstract Friendships between members of different ethnoracial groups can help to reduce prejudice and ease tensions across groups. A large body literature has explored possible determinants for the formation these friendships. One unexplored factor is role an individual’s skin color in influencing their opportunities befriend other This study seeks answer two questions: For minorities, how asso...
