What impacts skin color in digital photos?

چکیده
Skin colors are important for a broad range of imaging applications to assure quality and naturalness. We discuss the impact of various metadata on skin colors in images, i.e. how does the presence of a metadata attribute influence the expected skin color distribution for a given image. For this purpose we employ a statistical framework to automatically build color models from image datasets crawled from the web. We assess both technical and semantic metadata and show that semantic metadata has a more significant impact. This suggests that semantic metadata holds important cues for processing of skin colors. Further we demonstrate that the refined skin color models from our automatic framework improve the accuracy of skin detection.

Skin color. Could it be a new fingerprint?
OBJECTIVE To prove that the difference in human skin color can be used as a new fingerprint. METHODS A cross-sectional descriptive study was conducted in the Faculty of Medicine, The National Ribat University, Khartoum, Sudan between January and June 2010. The study consists of 139 subjects, which includes 41 Sudanese identical twins (82 subjects), 50 subjects from the general population, and...
متن کاملMultiscale Total Variational Alggorithms for Denoising Natural Color Photos in Digital Photography
As digital photography rapidly replacing the traditional film photography as the photography of choice for all but a few devoted professionals, post image processing of natural color photos such as denoising becomes increasingly an integral part of digital photography. Although many denoising schemes have been designed, almost none specifically target natural color photos. Noise in natural colo...
متن کاملSkin Color Analysis in HSV Color Space and Rendering with Fine Scale Skin Structure
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...
متن کاملColor balancing of digital photos using simple image statistics
The great diffusion of digital cameras and the widespread use of the internet have produced a mass of digital images depicting a huge variety of subjects, generally acquired by unknown imaging systems under unknown lighting conditions. This makes color balancing, recovery of the color characteristics of the original scene, increasingly difficult. In this paper we describe a method for detecting...
