Claim One:
1. A method for color correcting a digital image, the method comprising: identifying, by a color correction computing device, an area of interest in a digital image comprising a plurality of pixels, the identified area of interest comprising one or more facial areas; identifying, by the color correction computing device, at least a hair area and an eye area in the identified area of interest; determining, by the color correction computing device, a refined hair area in the identified area of interest based on the identified hair area, wherein the determining the refined hair area comprises: computing, by the color correction computing device, at least a lightness value (L) and a chroma value (C) for each pixel in the identified hair area; determining, by the color correction computing device, a data point value (D) for each pixel in the identified hair area based on the computed lightness value and the computed chroma value; applying, by the color correction computing device, a smoothing filter to data point value (D) for each pixel in the identified hair area to determine a smoothed data point value (D S ) for each pixel in the identified hair area; calculating, by the color correction computing device, a D S mean value (D S-mean ), a D S maximum value (D S-max ), and a D S minimum value (D s-min ) for the identified hair area; determining, by the color correction computing device, a threshold value (T) for the identified hair area based on the calculated D S mean, D S maximum, and D S minimum values; and identifying, by the color correction computing device, the refined hair area based on the determined threshold value; determining, by the color correction computing device, a white point in the eye area of the identified area of interest; determining, by the color correction computing device, based on the determined white point and a destination white point, one or more corrected colorimetric data points for each of the plurality of pixels in the identified area of interest; and correcting, by the color correction computing device, one or more output colors in the digital image using the determined one or more corrected colorimetric data points.
