Much attractiveness research has focused on face shape. The role of masculinity (which for adults is thought to be a relatively stable shape cue to developmental testosterone levels) in male facial attractiveness has been examined, with mixed results. Recent work on the perception of skin color (a more variable cue to current health status) indicates that increased skin redness, yellowness, and...

abstract this study was carried out in japan for evaluation of the relationship between phenolic compounds and skin color indices of 3 apples cultivars including ‘fuji’, ‘jonathan’ and ‘jonagold’, in 2006. in ‘jonathan’, l* (lightness) increased with decreasing red color of skin. in ‘jonagold’, chroma increased with increasing red color. but in ‘fuji’, there was no detectable difference between...

One of the outstanding features of polycythemia vera is the color of the skin. Clinical descriptions employ the terms brick red, congestive facies, cyanosis and erythrosis. Vaquez, who reported the first observed case of this disease, noted cyanosis as the prevailing tint. Osler thought that the color change was not that of cyanosis but congestion or redness. Since the microscopic investigation...

When skin areas like faces and hands are imaged under natural environments their color appearance is frequently affected by variations in illumination intensity and chromaticity. In color-based skin tracking and detection, changing intensity is often dismissed either with the use of normalized, intensity-invariant color coordinates or by additionally modeling possible skin intensities. Chromati...

A novel approach for real-time skin segmentation in video sequences is described. The approach enables reliable skin segmentation despite wide variation in illumination during tracking. An explicit second order Markov model is used to predict evolution of the skin color (HSV) histogram over time. Histograms are dynamically updated based on feedback from the current segmentation and based on pre...

Evolutionary psychologists have proposed that preferences for facial characteristics, such as symmetry, averageness, and sexual dimorphism, may reflect adaptations for mate choice because they signal aspects of mate quality. Here, we show that facial skin color distribution significantly influences the perception of age and attractiveness of female faces, independent of facial form and skin sur...

Pigmentation is a readily scorable and quantitative human phenotype, making it an excellent model for studying multifactorial traits and diseases. Convergent human evolution from the ancestral state, darker skin, towards lighter skin colors involved divergent genetic mechanisms in people of European vs. East Asian ancestry. It is striking that the European mechanisms result in a 10-20-fold incr...

The efficient human skin detection method is more suitable for many human skin colors with different illumination conditions which is used to skin segmentation. There are many human skin –color detection methods were available but they were not performing efficient with different ethnic. These are algorithm is based on skin colour detection. One of the problems this and similar algorithms have ...

Human ovulation is not advertised, as it is in several primate species, by conspicuous sexual swellings. However, there is increasing evidence that the attractiveness of women's body odor, voice, and facial appearance peak during the fertile phase of their ovulatory cycle. Cycle effects on facial attractiveness may be underpinned by changes in facial skin color, but it is not clear if skin colo...

It is widely accepted that skin-color is an effective and robust cue for face detection, localization and visual tracking. Well-known methods of color modeling, such as histograms and Gaussian mixture models enable creation of appropriately exact and fast detectors of skin. In particular, skin color-based methods are robust to changes in scale, resolution and partial occlusion. In real scenario...
