Flow Chart Skin color detection Denoise Lips color detection Image Face check Output Image

Skin Color Detection R > G > B, R-G > 15, R > 95, G > 40, B > 20

Denoise

Lips Color Detection

Face Check 7 faces detected

Other Results 1 faces detected2 faces detected3 faces detected

Conclusions  The color of lips is sensitive to the luminance  It’s impossible to detect if the lips were blocked by other object  Hard to detect profile
