Description

"Method and device for computer-aided hair treatment consultation"

The invention relates to a method and a device for computer-aided

Hair treatment advice.

Although users can use applications (apps) of their so-called "smart devices" (for example, smartphones, phablets or tablets) to visualize new possible hair dyes (colorations) and / or hairstyles, but usually only in a very simple form with not all available Color nuances of the colorations.

Often, no initial hair colors can be detected, and / or a current hair color of the user can not be registered.

In addition, no recommendations can be made for colorings that match the complexion (complexion) of the complexion (complexion).

In addition, no hairstyles that would fit into a head shape can be recommended.

In addition, it may be that a hair damage is not taken into account when recommending a coloring.

In various embodiments, a method is provided, for example using an app, which can more specifically help to find a suitable hair coloration with the right color shade.

In various embodiments, a photo may be provided by the application (e.g., app, e.g., for smart devices), e.g. be taken from a library, or directly by means of a digital camera, e.g. of the smart device.

The software (app) can be set up in various embodiments to recognize the hair shown in the photo and by means of an automatic and / or manual

White balance (if necessary by means of a color chart) a current hair color and a

(Facial) skin color to determine. In various embodiments, a user may indicate whether he has hair that has not been previously colored, or whether his hair has already been colored.

For indicating an existing hair color shade obtained by hair coloring, a plurality of typical shades and / or precise shades of hair color series may be provided for selection by the user.

In addition, it can be indicated in various embodiments, when the last hair dyeing took place, and / or how high a proportion of gray in the hair.

Hair dye results based on the initial hair condition 330AFH and determining at least one hair color result 332C associated with the skin color 330FG based on the plurality of hair color results and the skin color 330FG combined, such that, by way of example, 10 different hair colorant compositions 340 are illustrated, of which 10 accordingly but only those four hair coloring results 332C1, 332C2, 332C3 and 332C4 are shown, which are associated with the skin color 330FG of the user 330.

In various embodiments, determining the at least one hair color result 332C associated with the skin color 330FG may be accomplished using a randomization protocol derived by empirical examinations.

To determine the ZuOrdnungsvorschrift can be determined in various embodiments in empirical studies, which combination of (eg in a color space, eg the L ^* a ^* b or the CIELAB color space parameterized) hair and skin colors of

Viewers as appropriate, and what combinations are not. In various embodiments, the ZuOrdnungsvorschrift determined for a plurality of skin color regions may each have at least one associated hair color or at least one associated hair color range.

In determining the at least one hair coloring result 332C assigned to the skin color 330FG, the at least one associated hair color or the at least one assigned hair color range can be determined in various embodiments by means of the adjunct rule for the determined skin color 330FG, and only the one associated with the at least one hair color result 332C associated with the skin color 330FG or which hair color result (s) is determined, which at the same time is also a hair color associated with skin color 330FG.

For example, with very pale skin color 330FG, a deep black hair color may be considered inappropriate, so that the code for the very paler skin color 330FG has no black hair color. Accordingly, the hair coloring result 332C associated with at least one skin color would have no black hair color, although in view of the initial hair condition and the plurality of hair colorant compositions provided, achieving a black hair color would be possible for the user 330.

In various embodiments, the method may further include displaying (at 150) the at least one hair color result 332C associated with the skin color 330FG.

The display can be done in various embodiments by means of a display and / or a printer and / or by means of another suitable device.

Face 330KF of user 330 (in 120).

The determination of the 330KF face 330 of the user 330 may vary

Embodiments include determining a face area 330SG in the photo 332 representing the user 332, and possibly positions / sizes, etc. of other areas on the face, e.g. the eyes, the hairline, etc. Based on the determined areas, positions, sizes, etc. can be made in various embodiments, a parameterization of the face of the user 330, for example, based on a size ratio of face width to face height, position of a hairline expressed as a proportionate distance to one

Total head height of a head top, etc.

In various embodiments, the method may further comprise determining at least one hairdressing result 332S based on the initial hairstyle 330ASH and the face shape 330KF of the user 330 (in 430).

For the determination of the hairstyle result 332S, a plurality of hairstyles 540 may be provided. Determining the at least one hairstyle result based on the initial hairstyle 330ASH and the user's face shape 330KF may be accomplished in various embodiments using exclusion criteria and an ordering rule.

The exclusion criteria may be configured in various embodiments such that any desired hairstyle result 332S may not be achievable from any arbitrary style hairstyle 332ASH. For example, hair extensions can be excluded, so that by means of an exclusion criterion target hairstyles can be excluded which have a greater hair length than the starting hairstyle 332ASH. Similarly, for example, certain hair shaping methods may be excluded, for example, a smoothing method, a haircut, or the like. The exclusion criteria may differ in different

Embodiments may be designed as selectable by the user 330.

In various embodiments, inclusion of the face shape 330KF of the user 330 may be used for an assignment rule obtained by empirical examinations.

In order to determine the ZuOrdnungsvorschrift can be determined in various embodiments in empirical studies, which combination of face shape and hairstyle of viewers is rated as appropriate, and which combinations not.

In various embodiments, the adjunct provision determined therefrom may have at least one associated hairstyle for each of a plurality of face shapes or groups of face shapes.

When determining the at least one hairstyle result based on the initial hairstyle 330 ASH and the face shape 330KF of the user 330, the at least one associated hairstyle can be determined in various embodiments by means of the adjunct rule for the determined face shape 330KF, and as the at least one hairstyle result 332S only that or those Hairdressing result (s) are determined, which (s) at the same time satisfy both the selection criteria and the ZuOrdungsvorschrift.
