1. A method for measuring a feature of persons, the method comprising:
defining the feature of persons being measured;
measuring values of data points from a sample of digital images comprising the persons, according to the defined feature by a first algorithm;
generating a distribution curve of the measured values;
determine if the distribution curve is normal or even;
normalize the distribution curve by implementing monotonous transformation if it is determined that the distribution curve is not normal or even; and
standardizing the measured values, by implementing a hyperbolic tangent function transformation.
