Purpose: This study aims to reduce the failure rate due to excessive surgery (procedure) by consumers who want to satisfy their appearance through cosmetic plastic surgery. Most plastic surgery consumers want to know their face (especially their eyes and eyebrows) in advance to achieve results that look physiognomically good ahead of procedures or surgery. Until now, however, the characteristics of each part cannot be objectively converted into data. Therefore, we intend to develop a system so that the specific part of the face to be identified can be examined before surgery (procedure). The system allows you to immediately grasp the current physiognomic results and appearance status while automatically recording feature points in coordinates when you show your face on the screen of a mobile device. Again, the purpose of this study is to prevent wrong judgment and failure in performing surgery (procedure) through the development of such a system. Method: First, the name of each part of the feature points constituting the eyes and eyebrows was designated as a point on the coordinate plane. Second, the six types of eyes and eyebrows were first defined by equation. By substituting the input coordi-nates into this equation, a criterion for determining what shape the user s eyebrows fit was presented. In addition, it is possible to determine what shape the user s eyes are according to the coordinates of the eyes. Third, by substituting the coordinates of the eyes and eyebrows, the length and position of the eyes were com-pared with the position of the eyebrows to determine the image state of the physiognomy and cosmetic plastic surgery, and to what extent it is allowed in surgery (procedure) was suggested. Results: Since eyes and eyebrows are the most important parts of one s physiognomy (appearance), a method for setting standards that allow immediate judgment of each shape was suggested. The equation was defined according to the shape of the eyes and eyebrows, and when the coordinates were input, it was possible to deter-mine which shape they were, so that good results could be derived. Conclusion: In physiognomy, the color of the pupils and the degree of clarity of the eyes are important. Eyes can be said to be windows to the mind, and they are important parts of judging one s personality and character because they convey thoughts. Eyebrows, along with the eyes, are in an important position to determine large parts of physiognomy and beauty. There are times when you have to decide on surgery for better physiognomy and appearance, but it takes time and effort to learn the correlation between your eyes and eyebrows professionally. Therefore, if you have a tool to analyze it when you do not have knowledge on physiognomy (appearance), you can expect much more efficient results. Based on this paper, it is believed that it will be possible to establish a system that presents the direction or limitations of physiognomy (appearance) and surgery (procedure) because the user s appearance image status can be immediately known by reflecting eyes and eyebrows on the screen of devices.
