Locating skin pixels in images or video sequences where people appear has many applications, specially those related to Human-Computer Interaction. Most work on skin detection is based on modelling the skin on different color spaces. This paper explores the use of texture as a descriptor for the extraction of skin pixels in images. For this aim, we analyzed and compared a proposed color-based s...

Pigmentation of the skin, hair, and eyes varies both within and between human populations. Identifying the genes and alleles underlying this variation has been the goal of many candidate gene and several genome-wide association studies (GWAS). Most GWAS for pigmentary traits to date have been based on subjective phenotypes using categorical scales. But skin, hair, and eye pigmentation vary cont...

Determining the mechanistic and genetic basis of animal coloration is essential to understand the costs and constraints on color production, and the evolution and maintenance of phenotypic variation. However, genes underlying structural color and widespread pigment classes apart from melanin remain largely uncharacterized, in part due to restricted taxonomic focus. We combined liquid chromatogr...

Detecting the human skin and its analysis has number of important applications. This is a challenging task as. in images, the skin color is quite sensitive to the chrominance and intensity of the pixels. So the techniques with a single model for skin fail to cope up with the variation in skin colors because of ethnicity, age, lighting etc. This paper proposes a novel technique for skin detectio...

The success of invasive species is frequently attributed to phenotypic plasticity, which facilitates persistence in novel environments. Here we report on experimental tests to determine whether the intensity of cryptic coloration patterns in a global invader (brown trout, Salmo trutta) was primarily the result of plasticity or heritable variation. Juvenile F1 offspring were created through expe...

In this review article we summarize current knowledge on how variation on the DNA level influences human pigmentation including color variation of iris, hair, and skin. We review recent progress in the field of human pigmentation genetics by focusing on the genes and DNA polymorphisms discovered to be involved in determining human pigmentation traits, their association with diseases particularl...

We address the problem of identifying color variation in color skin lesion color. We adapt a spatial data mining method to this task and integrate with a segmentation method to identify significant color regions in an image. The resulting regions are compared with human perception via Kappa statistical test. Evaluation of the results indicate that the method approximates human judgment well and...

introduction: melanin pigmentation in the oral mucosa occurs as a result of several reasons one of which is smoking. cigarette smoke induces numerous side effects in the people who do not smoke, but are in the same environment. the aim of this study was to evaluate the role of parental smoking on pigmentation of their children's oral mucosa. materials and methods: this study was carried out as ...
