Abstract

A system and method for providing a personalized digital face chart. A digital image of a subject'"'"'s face is obtained. A facial region of the digital image is identified from a background region of the digital image. A line drawing is generated based on at least the facial region of the digital image. The line drawing is stylized to generate a personalized digital face chart. A user interface configured to accept at least one face chart modification from a user is provided. The personalized digital face chart is modified based on the at least one face chart modification.

Claims

1. A computer-implemented method for providing a personalized digital face chart comprising:

obtaining a digital image of a subject'"'"'s face;

identifying a facial region of said digital image from a background region of said digital image;

generating a line drawing based on at least said facial region of said digital image;

stylizing said line drawing to generate a personalized digital face chart;

providing a user interface configured to accept at least one face chart modification from a user; and

modifying said personalized digital face chart based on said at least one face chart modification.

2. The computer-implemented method of claim 1, wherein said at least one face chart modification comprises manually choosing a feature style for a selected feature characteristic from a selection of feature styles.

3. The computer-implemented method of claim 2, wherein said selected feature characteristic comprises an eye shape.

4. The computer-implemented method of claim 2, wherein said selected feature characteristic comprises an eye crease.

5. The computer-implemented method of claim 1, wherein said user interface comprises at least one slider associated with a parameter of said personalized digital face chart, wherein said at least one face chart modification comprises a change in position in said at least one slider affecting said parameter.

6. The computer-implemented method of claim 1, wherein said user interface comprises at least one slider associated with a degree of stylization of said personalized digital face chart, wherein said at least one face chart modification comprises a change in said degree of stylization.

7. The computer-implemented method of claim 1, wherein generating said line drawing based on said at least one facial region comprises generating a line drawing of a hair area of said subject by:

obtaining at least one foreground selection comprising said hair area of said subject in said digital image;

obtaining at least one background selection excluding said hair area of said subject in said digital image;

determining a calculated hair area of said digital image, wherein said calculated hair area is determined based on said foreground selection and said background selection; and

generating a line drawing of said hair area based on said calculated hair area.

8. The computer-implemented method of claim 7, wherein said digital image of said subject is taken with said subject in front of a monochromatic backdrop and wherein said background selection is determined using at least one chromakeying technique.

9. The computer-implemented method of claim 1, further comprising evaluating a hair area of said digital image for the presence of at least one hairstyle feature, wherein generating said line drawing comprises rendering at least one curve associated with said hair area, wherein said at least one curve comprises at least one curve discontinuity associated with said at least one hairstyle feature.

10. The computer-implemented method of claim 9, wherein said at least one hairstyle feature is selected from the group consisting of a hairline shape, a widows peak, and a part.

11. The computer-implemented method of claim 1, wherein said digital image is obtained using an imaging device comprising a photographic flash placed above said imaging device, and wherein said identifying said facial region comprises determining a chin location based on a defined shadow in said digital image.

12. The computer-implemented method of claim 1, further comprising obtaining three-dimensional data of said subject obtained with at least one three-dimensional imaging device, wherein said three-dimensional data of said subject is used to identify said facial region of said digital image from said background region of said digital image.

13. The computer-implemented method of claim 1, wherein said at least one face chart modification comprises an omission of one or more omitted features.

14. The computer-implemented method of claim 1, wherein said user is said subject.

15. The computer-implemented method of claim 1, wherein said user is a beauty expert.

16. The computer-implemented method of claim 1, further comprising the step of generating a plurality of control points associated with at last one facial feature of said subject, wherein said line drawing is generated based on said plurality of control points,

wherein said user interface comprises a display area showing said plurality of control points, wherein said at least one face chart modification comprises adding, moving or removing one or more of said plurality of control points to modify said line drawing.

17. The computer-implemented method of claim 1, further comprising the steps of:

obtaining an infrared image of said subject illuminated by an infrared illuminant source; and

determining an eye position of said subject in said digital image based on infrared intensity in said infrared image;

wherein said eye position is used to identify said facial region of said digital image from said background region of said digital image.

18. The computer-implemented method of claim 1, wherein stylizing said at least one face chart comprises modifying a facial expression of said subject.

19. The computer-implemented method of claim 1, wherein said at least one face chart modification comprises manually selecting a facial expression.

20. The computer-implemented method of claim 1, further comprising the step of colorizing said personalized digital face chart based on one or more colors in said digital image,

wherein said at least one face chart modification comprises changing a coloring of said personalized digital face chart.

21. The computer-implemented method of claim 1, further comprising the step of storing an intermediate representation of said personalized digital face chart capable of generating a plurality of digital face chart versions using said user interface.

22. The computer-implemented method of claim 1, wherein said user interface is configured to display a plurality of products in response to user input associated with said personalized digital face chart.
