Description

Technical Field

[0001] The present invention belongs to the technical field of LED intelligent lighting, and in particular relates to a method and system for predicting the sexual attractiveness of lipstick based on gender, color system, and light source correlated color temperature. Background Art

[0002] Lipstick has always been one of the most commonly used cosmetics for women. As the basic attribute of lipstick, the relationship between color and attractiveness has long attracted much attention. The main color of lipstick is orange-red, which enables it to exert the red sexual effect and enhance the user's sexual attractiveness in the corresponding relationship context. The so-called red sexual effect refers to the visual sense of approach and expansion brought by the physical properties of red, which easily triggers excitement, excitement, and tension. Psychologists have found that when people combine women with red, they tend to associate it with passion, desire, and romance. Therefore, there is a very close relationship between lipstick and sexual attraction. Within the main color, lipstick numbers of different color systems have certain differences in brightness and hue, which will inevitably affect their sexual attractiveness to a certain extent. Therefore, it is very valuable to analyze the sexual attractiveness of different lipstick color systems and further explore the correlation and degree of association between the two.

[0003] At the same time, the rapid development of LED intelligent lighting technology has promoted people's perception of light quality. Compared with traditional light sources, LED light sources have many advantages such as high light efficiency, low radiation, and long life, and its technical characteristics of adjustable light color have created possibilities for intelligent lighting. We also need to note that the color perceived by the human eye comes from the combined effect of objects and light sources. Therefore, under the interaction of different light sources and lipstick, the feelings brought to people will also be slightly different. Therefore, the influence of light sources is also important for the visual appeal of lipstick.

[0004] In addition, due to the inherent visual gender differences between men and women, as well as the different perception dimensions of sexual attraction between the same sex and the opposite sex, the necessity of conducting separate studies on different genders is highlighted.

[0005] In summary, it is of great significance to scientifically and rationally design a lipstick attractiveness prediction method for gender, color and light source. Summary of the invention

[0098]

[0099] p1=4.636

[0100] p2=-1.742×10 6

[0103] In order to further confirm the technical advantages of the method of the present invention in predicting the sexual attractiveness of lipstick, a psychophysical experiment was used to calculate the PEARSON correlation coefficient between the sexual attractiveness of lipstick colors for men, women and the general population obtained from the psychophysical experiment and the three types of lipstick sexual attractiveness prediction estimates M1, M2, and M3 in 6). The specific implementation is: using the above 5 types of light sources to be used as experimental light sources and the above 3 popular lipstick colors as experimental objects, a psychophysical experiment was carried out, and the specific experimental method is as follows:

[0104] 1) The experiment was conducted in a dark room, with a gray background cloth around the experimental area. The three popular lipstick colors mentioned above were used as experimental objects, and a female was used as an experimental model. During the experiment, the lipstick was applied to the lips to simulate the real use scenario of lipstick. At the same time, the model wore an eye mask throughout the experiment to cover other facial features as much as possible to avoid interference. Two intelligent LED light sources were respectively at a 45° angle to the central axis of the experimenter to evenly illuminate his face. Each light box was equipped with light-emitting hardware on the top to generate the specified experimental light source. The observer can move freely in the specified area of ​​the experiment, so as to comprehensively and carefully observe the color of the model's lips after applying lipstick.

[0105] 2) During the experiment, the experimenter will change the model's lipstick color and the correlated color temperature of the experimental light source in a specified order. The observer needs to record the evaluation of the model's lip color in each experimental scene in the experimental record sheet according to the evaluation rules specified in the experiment. The evaluation rules are as follows:

[0106] The seven-level evaluation is used, with 1 for very unattractive and 7 for very attractive. The larger the number, the higher the degree of sexual attraction. After the observer observes the lipstick color of the experimenter for a period of time, the observer can make a corresponding score. At the same time, other experimenters will continue to remind the observer to pay attention to the lipstick color of the model's lips as much as possible and eliminate the interference of other facial features.

[0107] 3) A total of 60 observers were selected for the experiment, with a male-female ratio of 1:1, and all had normal vision. Before each experiment, the experimenter will introduce the experimental situation orally. During the experiment, the observer observed the lipstick color of the model's lips under the corresponding light source and made a sexual attractiveness evaluation, and then closed his eyes until the experimenter changed the next set of lipstick colors and experimental light sources. The observer observed again for a period of time and made a sexual attractiveness evaluation, and repeated this step until the last set of experimental scenes. A total of 5 (light source) * 3 (lipstick color) = 15 sets of experimental scenes.

[0108] 4) After the experiment, the sexual attractiveness evaluation scores of all observers for the lipstick color are counted to calculate the PEARSON correlation coefficient between the subjective evaluation value and the lipstick sexual attractiveness prediction estimate constructed by the present invention. The experimental results are shown in Table 1 below, where a larger value indicates a higher sexual attractiveness score of the lipstick on the lips under the lipstick-light source combination.

[0109] Table 1 Experimental results of observers’ subjective evaluation of sexual attractiveness

[0110]

[0111] Through the above psychophysical experiment, the subjective evaluation values ​​of sexual attractiveness of different gender observers for different light sources and lipstick color combinations can be obtained, and the PEARSON correlation coefficients between the subjective evaluation values ​​and the three types of lipstick sexual attractiveness prediction estimates M1, M2 and M3 constructed by the present invention are further calculated, as shown in the following Table 2. The results show that the correlation coefficients between the subjective evaluation values ​​and the model estimation values ​​are all above 0.9, proving that the lipstick sexual attractiveness prediction models based on gender, color system and light source correlated color temperature constructed by the present invention have extremely high accuracy, and further proving that the method of the present invention has a strong technical advantage in predicting the sexual attractiveness of lipsticks.
