skin color
The method is based on the assumption that faces are well separated from the background by skin color detection.
      
H is selected as the basic recognition parameter because its value has a narrow range for the skin color and can keep stable while the illumination intensity or the curvature of skin surface is changing.
      
It is firstly found that the mean of saturation and value (S+V)/2 can keep stable when the illumination intensity is changed or the skin surface is inflected, and (S+V)/2 changes with skin color, but the tendency of change is contrary to that of H.
      
African slaves of Europeans are most commonly associated with images of exploitation as brute labor or domestic servants, as marginalized and discriminated against on the basis of their skin color, and perceived of as of inherently lower status.
      
Some individual characteristics, such as skin color or phenotype, are an obvious holdover from colonial times.
      
This study draws upon immigrant incorporation theories to investigate whether native origin trumps skin color in shaping the racial identities of black migrants.
      
The skin color depends mainly on the amount and distribution of melanophore and iridophore, as xanthophore is quite rare.
      
We examined repeated measures of carotenoid-dependent skin color and blood parasitism in American kestrels (Falco sparverius) to distinguish whether coloration might signal current parasitism or the potential to deal with infections in the future.
      
An RFLP linkage map of the potato is presented which comprises 304 loci derived from 230 DNA probes and one morphological marker (tuber skin color).
      
Identification of co-dominant RAPD markers tightly linked to fruit skin color in apple
      
After testing the primer in four populations, two fragments were found to be associated with red skin color and another two fragments associated with yellow skin color.
      
In the 'Rome Beauty' x 'White Angel' population, two fragments were associated with red skin color; one fragment designated as A1 (1160 bp) was from 'Rome Beauty' and another fragment (A2, 1180 bp) was from 'White Angel'.
      
In three other crosses tested, only fragment A1 co-segregated with red skin color; two fragments, a1 and a2 (1230 bp and 1320 bp), were associated with yellow skin color.
      
Examination of amplification products in 56 apple cultivars and advanced breeding selections demonstrated that the universal primers could be used to correctly predict fruit skin color in most cases.
      
A fluorogenic 5' nuclease (TaqMan) assay to assess dosage of a marker tightly linked to red skin color in autotetraploid potato
      
This report examines the effect of human selection on variable skin color by examining the variation present in the gene VvmybA1, a transcriptional regulator of anthocyanin biosynthesis.
      
Distant flaps or tube pedicles were used but the result was not good in terms of skin color match and texture.
      
A simple and effective method of monitoring a free skin flap transfer when the flap skin color is white in spite of having a good blood circulation is described.
      
It is easy to confirm that the anastomosed vessels are patent or not by visualizing the flap skin color, because erythema will appear after topical application of dinitrochlorobenzene even if skin color is white.
      
Consequences of skin color and fur properties for solar heat gain and ultraviolet irradiance in two mammals
