Human skin color can be defined in different color ranging
from whitish to brownish. Color space selection is crucial in
pixel classification technique, as different color space describes
color in different ways. Basically a color is defined into a
specific color space, it represent the combination of three or
four different color component. Such as CMYK color space
[14], a color is separated into cyan(C), magenta(M), yellow(Y)
and black(K). Among all the color spaces, RGB color space
has chosen in our approach. RGB is primary addictive model
formed by three main color, which is red(R), green(G) and
blue(B) as primary stimuli for human color perception.
