First Claim
Patent Images
1. A method for determining skin characteristics and cosmetic features using color analysis, comprising:
- analyzing the color of skin images in a pixel by pixel manner in a Red-Green-Blue (RGB) color system for an acquired digital image;
converting colors obtained in a device-dependent RGB color system into a device-independent standard RGB color system (sRGB);
generating a sample of most frequent sRGB colors responsive to analyzing the color of skin images in a pixel by pixel manner in the sRGB color system for the acquired digital image;
modeling the standard red, green, and blue component color distribution with Gaussian probabilistic distribution with estimated parameters (expected value and standard deviation) on the generated sRGB color sample for the acquired digital image; and
generating a phototype of the skin through a decision tree unit responsive to the estimated distribution model parameters colors.
