The paper proposes a novel algorithm to dynamically define the Region of Interest (ROI) videophone application. The algorithm uses the color information Hue and Cr to find the skincolor pixels and also use range of threshold obtained from red and blue components in normalized RGB color space to remove nonskincolor pixels because the human skin tends to have a predominance of red and non-predomi...

Skin color based tracking techniques often assume a static skin color model obtained either from an offline set of library images or the first few frames of a video stream. These models can show a weak performance in presence of changing lighting or imaging conditions. We propose an adaptive skin color model based on the Gaussian mixture model to handle the changing conditions. Initial estimati...

BACKGROUND 3,4,5-Trihydroxybenzoic acid glucoside (THBG), a molecule produced by an original biocatalysis-based technology, was assessed in this study with respect to its skin photoprotective capacity and its skin color control property on Asian-type skin at a clinical level and on skin explant culture models. METHODS The double-blinded clinical study was done in comparison to a vehicle by th...

The human skin color is one of the most perceptible phenotypic variations among humans and is determined primarily by the type and amount of melanin synthesized within melanosomes and the pattern of melanosome distribution within the melanocytes. Getting a lighter skin tone always draws a lot of interest, as for centuries, fair or light skin color has been a symbol of prominence, superiority an...

In the aftermath of Western colonization is the trivialization of skin color as significant issue in the psychology of peoples of African descent. Although social scientists use race as a key factor in elucidating and understanding human social conditions, skin color and its impact on the social and psychological disposition of people of African descent have been understudied. Oblivious to the ...

Skin region detection plays an important role in a variety of applications such as face detection, adult image filtering and gesture recognition. To improve the accuracy and speed of skin detection, in this paper, we describe a fast adaptive skin detection approach that works on DCT domain of JPEG image and classifies each image block according to its color and texture properties. Main contribu...

Among many skin color sources, hemoglobin and melanin components are regarded most significant in determining the final color of human skin. In extracting the two components, this paper proposes to use a more intuitive color model, HSV, than the RGB color space. For 3D rendering, we propose a novel method to reconstruct the fine-scale structure (normal map) of the human skin from a single highl...

Skin cancers are cancers that due to the development of abnormal cells that have the ability to invade or spread to other parts of the body. There are three main types: basal-cell cancer, squamous-cell cancer and melanoma. Among the three melanoma spreads through metastasis, and therefore it has been proved to be very fatal. Melanomas typically occur in the skin and identification of skin cance...

Skin detection remains a challenging task over several decades in spite of many techniques evolved. It is the elementary step of most of the computer vision applications like face recognition, human computer interaction, etc. It depends on the suitability of color space chosen, skin modeling and classification of skin and non-skin pixels under varying illumination conditions. This paper present...
