Carotenoids typically need reflective background components to shine. Such components, iridophores, leucophores, and keratinand collagen-derived structures, are generally assumed to show no or little environmental variability. Here, we investigate the origin of environmentally induced variation in the carotenoid-based ventral coloration of male common lizards (Lacerta vivipara) by investigating...

Red tilapia is becoming more popular for aquaculture production in China in recent years. However, the pigmentation differentiation in genetic breeding is the main problem limiting its development of commercial red tilapia culture and the genetic basis of skin color variation is still unknown. In this study, we conducted Illumina sequencing of transcriptome on three color variety red tilapia. A...

The applications of skin color recognition are extended in utilizations both in content based analysis and human computer interactions. Therefore, achieving a useful method for segment the skinlike pixels can help the presented problems. In this paper a hybrid PSOGSA -ANN is proposed as a new training method for Feed forward Neural Networks (FNNs) in order to investigate a high efficiency for s...

The content of this paper is the proposal of two techniques for the modeling of skin color in images using a combination of spaces of colors HSV with YCbCr and HSV with CIELab. To determine the intervals of pixels nonskin color uses the components H and S, on the other hand, the intervals of pixels skin color uses the components Cb, Cr, a and b. There are compared the results of the technique H...

In this paper, a reliable method for detecting human faces in color images is proposed. This system firstly detects skin color in YCgCr and YIQ color space, then filters binary texture and the result is morphological processed, finally converts skin tone to the preferred skin color configured by users in YIQ color space. The real-time adjusting circuit is implemented and some of simulation resu...

background: nowadays, analyzing human facial image has gained ever-increasing importance due to its various applications. image segmentation is required as a very important and fundamental operation for significant analysis and interpretation of images. methods: among the segmentation methods, image thresholding technique is one of the most well-known methods due to its simplicity, robustness a...

A current concern in genetic epidemiology studies in admixed populations is that population stratification can lead to spurious results. The Brazilian census classifies individuals according to self-reported "color", but several studies have demonstrated that stratifying according to "color" is not a useful strategy to control for population structure, due to the dissociation between self-repor...

In the current era of World Wide Web, human skin detection is a critical parameter in computer vision and image processing applications. With diverse range of applications in forensic sciences, medical imaging, pornography filtering, image retrieval, video surveillance etc., skin detection algorithms are to face many challenges. The major problems in detection of human skin color are varying sh...
