Abstract

PROBLEM TO BE SOLVED: To elucidate the low of causality between the shape and actual age of an external aspect serving as a foundation for the estimation of the exact actual age or the exact regulation of the impression age. SOLUTION: The actual age is estimated with the form of wrinkles and/or sagging as an index. More preferably, the wrinkles of the forehead, the dents of the upper eyelids, crow's feet, the black rings beneath the eyes, the dents of the cheeks, nasolabial grooves, the wrinkles at the angle of the mouth, the sagging of the lower rack line and the wrinkles of the neck are exemplified. The existence shape of such wrinkles correlate well with the actual age. This technique is applicable to the index for treatment in beautification formation and the index of special makeup as well.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for estimating an actual age and a method for adjusting an impression age.

[0002]

2. Description of the Related Art Humans are social animals, and in order for humans to survive, they cannot avoid passing through other people.
It is indispensable to know the attributes of the other person in such a relationship with the person, but information such as age is indispensable information in the relationship such as the hierarchical relationship or what kind of honorifics are used. However, because it is taboo in itself, it was difficult to obtain information, and there was no other way but to deal with the source of the estimation. Such estimation is often inaccurate, and an accurate method of estimating the actual age has been required. Also, although everyone knows that there is a causal relationship between age and external appearance, it is not known at all what causal laws exist, and changes in external appearance Individual differences were large and, therefore, it was thought that it was extremely difficult to accurately estimate the actual age using the external appearance as an index because of the large variation.

[0003] On the other hand, in the fields of movies and theaters,
It is not uncommon for actors to play roles far from their actual age, and in such cases, the impression age is adjusted by make-up etc. according to the age set in the setting, but sometimes this adjustment is not successful He often went to work and hindered the story. In such a case, it is important to make makeup that looks like the set age, and the so-called special makeup technology itself that embodies morphological changes has been developed. The lack of guidance is believed to be a major cause. Formulation of such guidelines was desired.

[0004] The above-mentioned method of adjusting the impression age is not only in the fields of movies and theaters, but also in the field of cosmetic plastic surgery, for example. It is undeniable that accurate surgery may not be performed because the guidelines for how to enforce tarmi are not clear, and it can be said that developing an accurate adjustment method of impression age is a problem affecting society at large. .

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made under such circumstances, and the form and actual form of the external appearance, which form the basis for accurate estimation of the actual age or accurate adjustment of the impression age, have been made. The purpose is to clarify the causality between age and age.

[0006]

In view of such a situation, the present inventors sought a causal rule between the form of the external appearance and the actual age.
After extensive research efforts, they found a very good correlation between the form of wrinkles and / or tarmi and the actual age, and realized that this was the causal rule of the form of the external appearance and the actual age.
The invention has been completed. That is, the present invention relates to the following technology. (1) A method for estimating the actual age, wherein the form of wrinkles and / or tarmi is used as an index. (2) The method for estimating the actual age according to claim 1, wherein the form of wrinkles and / or lumps is the existence site and the degree thereof. (3) The method for estimating the actual age according to (1) or (2), wherein the degree of wrinkles and / or tarmi is determined by comparison with a reference photograph of a five-grade rating scale. (4) A method for adjusting the impression age, which comprises changing the form of wrinkles and / or tarmi. (5) The method of adjusting the impression age according to claim 4, wherein the form of wrinkles and / or tarmi is an existing part and its degree. (6) The method for adjusting the impression age according to (4) or (5), wherein the degree of wrinkles and / or tarmi is determined by comparison with a reference photograph of a five-grade rating scale. Hereinafter, the present invention will be described in more detail focusing on embodiments.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The method for estimating actual age according to the present invention is characterized in that the form of wrinkles and / or tarmi is used as an index. The form of existence includes wrinkles and / or
Alternatively, the degree of tarmi is a large factor, and it is preferable to use this. For the presence position, a generally known position may be used, and preferably, forehead wrinkles, upper eyelid depressions, corners of the eyes, wrinkles under the eyes, cheek depressions, nasolabial folds, mouth corner wrinkles, lower jaw A line tarmi and a neck wrinkle can be exemplified, and particularly preferably, one or two or more selected from the corners of the eyes, the wrinkles around the mouth, the nasolabial fold, and the forehead wrinkles can be exemplified. FIG. 1 shows images of these positions. By accurately determining these, the actual age can be accurately estimated. For these determinations, it is possible to apply the standard of wrinkle evaluation that is usually performed in the field of cosmetics,
Score 1 for the least severe, score 5 for the most severe
The following five-step criteria can be preferably exemplified. Such a standard is preferably determined by preparing a specific standard photograph in advance and comparing it. One example of such a reference photograph is shown in FIG. By weighting and calculating these scores, it is possible to more accurately estimate the actual age. Of course, the form of wrinkles and tarmi does not need to be based on such scores as scores, but it is also possible to use numerical values such as lengths and depths that represent specific shapes, etc. It is also possible to use numerical values obtained by taking quantification means such as quantification. Such a technique also belongs to the technical scope of the present invention.

[0008] Weighting for estimation can be performed by statistical processing. That is, if a sample having a spread in age is determined for the degree of wrinkles and / or tarmi at the site according to the above-described criteria, and a multiple regression analysis is performed, a regression equation can be obtained. It is possible to accurately estimate the actual age. Such an example will be described in an embodiment described later.

The method for adjusting the impression age according to the present invention utilizes the fact that the wrinkles and / or tarmi are well correlated with the actual age. It is characterized by eliminating or making it harder to see, or by giving wrinkles and / or pallets on the contrary to make the tongue look more. The rank of the wrinkles is determined by substituting the wrinkle and Talmi scores by trial and error using the rank to the wrinkle contribution, the regression equation, and the multiple correlation regression equation, and then the appearance age (impression age). Can be simulated, and the shape of wrinkles and tulmi of a corresponding age can be simulated, and the shape of the face can be adjusted based on this. Such a technique can be used as a guideline for treatment of cosmetic formation or a guideline for special makeup. Such changes can be virtually reproduced by using computer graphics, so that accurate postoperative predictions can be presented to the patient in cosmetic formation and the like.

EXAMPLES Hereinafter, the present invention will be described with reference to Examples.
As will be described in further detail, it goes without saying that the present invention is not limited to only such embodiments.

<Example 1> (Example of multiple regression analysis) A sample of 73 Japanese women in their 40s and 70s was used as a sample, and three beauty specialists compared the face photograph of the sample with the reference photograph shown in FIG. Due to wrinkles, Talmi scored. Multiple regression analysis was performed using this score value as an explanatory variable and the objective variable as actual age. Four variables were selected by the stepwise method. As a result, four explanatory variables, that is, wrinkles at the corners of the eyes, wrinkles around the mouth, nasolabial folds, and wrinkles on the forehead remained. The multiple correlation coefficient was 0.900 and the coefficient of determination was 0.811. These values are very close to 1 and
It is shown that the wrinkle and / or Talmi scores have a very good correlation with the actual age, and thus it can be seen that the actual age can be accurately estimated by evaluating such wrinkle and Talmi scores. The regression equation is as follows. Estimated age (actual age) = score of wrinkles of outer corner x 3.642
+ Nasolabial score x 2.244 + wrinkles around mouth x 1.7
39 + 22.838 The standard partial regression coefficient is 0.416 for wrinkles at the corners of the eyes, 0.249 for wrinkles around the mouth, 0.224 for the nasolabial folds, and 0.188 for wrinkles on the forehead. High contribution to In other words, in other words, it can be understood that the appearance age (impression age) can be easily adjusted by adjusting wrinkles and tarmi of these highly contributing portions.

Example 2 Face photographs of 47 women were mixed by morphing to create a 60-year-old mixed face. The wrinkle-removed face from which the wrinkles of each part were removed from this face was evaluated by 102 panelists for its age. When the wrinkle score of the average face was determined separately, the wrinkles of the outer corner of the eyes were 4.5, the nasolabial fold was 4, the circumference of the mouth was 3.5, and the forehead wrinkles were 4. When this was substituted into the estimation formula of Example 1 and the estimated age was calculated, it was 63.72 years old, and it was found that the estimation was extremely accurate. Furthermore, the estimated age of each wrinkle-removed face was calculated by substituting 1 into the wrinkle score of this estimation formula.
The results are shown in Table 1 as a comparison between panelists' judgment values and estimated values.
Shown in This shows that the estimation method of the present invention is appropriate. FIG. 3 shows the average face and the wrinkle-removed face at the age of 60.
