Abstract
A method and device for determining the color homogeneity of hair is provided. In accordance with various exemplary embodiments, a method comprises providing a digital image in which hair is depicted and which is parameterized in a color space which is defined by employing a parameter set in which one of the parameters is a hue, defining at least one hair analysis region in the digital image, determining a hue distribution in at least one hair analysis region, and determining at least one color homogeneity value on the basis of the determined hue distribution.
Claims20
A method for determining the color homogeneity of hair, the method comprising the steps of:
- providing a digital image in which hair is depicted and which is parameterized in a color space which is defined by use of a parameter set in which one of the parameters is a hue;
- defining at least one hair analysis region in the digital image;
- determining a hue distribution in the at least one hair analysis region;
- and
- determining at least one color homogeneity value on the basis of the determined hue distribution.
A device for determining the color homogeneity of hair,
- comprising:
- a data processing device;
- and
- a display device;
- wherein the data processing device is configured to:
- provide a digital image in which hair is depicted and which is parameterized in a color space that is defined by use of a parameter set in which one of the parameters is a hue;
- define at least one hair analysis region in the digital image;
- determine a hue distribution in the at least one hair analysis region;
- and
