Problems solved by technology

[0004] The technical problem solved by the present invention is to overcome the defects that there is no method for quantitatively evaluating the state of human face in the prior art, and the existing youth curve can only qualitatively evaluate the face of European and American people, and is not suitable for evaluating the face of Asian people, and provides a method for evaluating facial appearance. The method and application of observing age and facial aging degree

Embodiment 1

[0097] The present embodiment provides five methods for evaluating the apparent age of the face, i.e. method I~method V, which specifically include the following steps:

[0098] (1) The interviewees selected Chinese women who were healthy, with normal development and good facial features, and those who had facial diseases, scars, facial surgery, obesity or other people who might interfere with the research were excluded; interviewees were divided into one age group every 10 years Grouping (20-29 years old, 30-39 years old, 40-49 years old and 50-60 years old), with more than 60 people in each group, a total of 267 interviewees; interviewees fully understand the nature, purpose and research After the content, fill in the informed consent form; before collecting photos, each interviewee needs to fully clean his face, and rest for 15 minutes in a room with a temperature of 22±2°C and a relative humidity of 50-60%;

[0099] Then use the parallel-polarization mode of the facial pho...

Embodiment 2

[0127] The present embodiment provides five methods for evaluating the apparent age of the face, including method I~method V, and the specific steps are as follows:

[0128] (1) The evaluators were selected from Chinese women with good health, normal development and good facial features, excluding those with facial diseases, scars, facial surgery, obesity or other people who might interfere with the research, a total of 16 interviewees were selected; After fully understanding the nature, purpose and content of the research, the participants filled out the informed consent form; before collecting photos, each person to be evaluated had to clean his face thoroughly, and the conditions were set at a temperature of 22±2°C and a relative humidity of 50-60°C. 15 minutes of rest in the room;

[0129] Then use the parallel-polarization mode of the facial photo collection device Visia-CR to collect the frontal photos of each interviewee (that is, take the interviewee's facial nose brid...

Embodiment 3

[0149] The present embodiment provides the method for assessing the degree of facial aging, and the specific steps are as follows:

[0150] (1) Use the data analysis software SPSS Statistics 20.0 to carry out the paired t test to the actual age of the Chinese women in Example 1 and the estimated apparent age to obtain the p value of the significance analysis;

[0151] (2) If p<0.05, there is a significant difference between the apparent age of the group and the actual age, and it is judged that the apparent age of the person's face is significantly greater than the actual age; if p≥0.05, the apparent age of the group is There is no significant difference from the actual age, and it is judged that the apparent age of the person being evaluated is not significantly greater than the actual age; among them, the paired t-test results of the apparent age and actual age are shown in Table 3 below.

Abstract

The invention discloses a method for evaluating the apparent age of the face and the aging degree of the face and the application thereof. The method includes steps: (1) collecting facial photos of multiple interviewees; (2) performing length calibration and analysis on the photos to obtain x 1 and x 3 value, or x 2 and x 4 value, or x 3 and x 4 value, or x 1 and x 2 value, or x 1 、x 2 、x 3 and x 4 value; where x 1 is the distance from the starting point to the upper edge of the lower eyelid; x 2 is the distance from the intersection point of line 3 and line 4 to the midline of the lip; x 3 is the included angle between line 1 and line 2; x 4 is the angle between line 3 and line 4; (3) according to the actual age y' of the respondent and the obtained x 1 、x 2 、x 3 and / or x 4 (4) Calculate the apparent facial age y of the evaluator according to the obtained regression equation. This method can quantitatively evaluate the facial apparent age and aging degree of people in various regions, especially Asians, and has good reliability.

Description

technical field [0001] The invention relates to a method for evaluating the apparent age of the face and the aging degree of the face and its application. Background technique [0002] The aging face is an overall change gradually formed during the aging process of the face. With the relaxation of facial ligaments and the downward movement of soft tissues, phenomena such as periorbital enlargement, nasolabial fold deepening, and "fat" on the cheeks appear, resulting in changes in the facial contour curve. In the prior art, one or more points such as facial wrinkles, eyelid bags, and nasolabial folds are usually used to assess facial aging. However, these evaluation methods are too limited due to the small area studied, so it is necessary to develop a method to study facial aging from the whole area of ​​the face. [0003] In 2000, Little William proposed the youthful curve (youthful curve), a curve in the middle of the face that looks like the letter "S" when viewed from th...
