Certain Dimensions And Ratios Create Harmony In The Face Attractiveness Features!
To determine the Face Attractiveness Score, PinkMirror analyze the geometric proportions of facial features such as the eyes, nose, lips, etc. and the distance between those. When the face analysis is finished, you are able to see which features of your face determine your beauty score.
Beauty is in the balance of these face analysis features which artists from NeoClassical era called the Aesthetic principles. These aesthetic-principles are analyzed from the portraits and they are then drawn and extracted into two generic rules. The ‘Rule of Fifths’ and the ‘Rule of Thirds’.
Rule Of Fifths
A proportionate face may be divided vertically into fifths with each of those fifths being approximately the width of one eye. Aesthetic balance is considered ideal when the facial features fall within these parameters. The width of the base of the nose is approximately equal to the distance between the eyes.
Rule of Thirds
Leonardo da Vinci, that all-around genius of science and art, developed a formula for determining a well-balanced face. He found that a well-balanced face can be evenly divided into thirds, vertically. The top third is from your hairline to the top of your brows. The middle third is from the top of the brows to the bottom of your nose . The bottom third is from the bottom of your nose to your chin.
The Rule-of-Fifths and Rule-of-Thirds is a simple representation of a complex interplay of aesthetic measures between different parts of a beautiful face. We have to further analyze the face structure how these measures are correlated to between each other.
Face Structure Analysis
In the below image, you can see two faces. Amoung them which face you feel beautiful? The one on the left or the right one? For both the faces, the skin quality and expressions are the same. Then what makes the difference these two faces?
The following table showing the result of a statistical study on 10,000 faces. The aspects that make the big difference between an attractive face and non attractive face are the length of eye-brow, eye, forehead, nose length & width and chin length.
|eye-brow external distance||5554||5039||515|
|eye external distance||4365||4037||328|
|eye-brow average length||2140||1887||253|
|eye average length||1353||1212||141|
|eye to brow -outside-margin||896||781||115|
|eye inter distance||1680||1620||60|
|eye to eye-brow inside margin||872||819||53|
|eye-brow inter distance||1288||1287||1|
The unit used in this table is PCI (Photographic Canthal Index) .
The Beauty Scale
In this beauty scale, following aspects are considered.
- Skin quality.
Please note that the face attractiveness score system with PinkMirror has limitations so it is not final. Beauty is the proportion of the whole face, rather than just with the individual features so please use these values only for fun.
Score – [0 ~ 1]
With this face analysis score, the results may determine a very unattractive face because there is hardly any symmetry with the features. It also may be because the face detection had gone wrong.
Score – [1.0 ~ 2.9]
With this face analysis score, the results determine an unattractive face because the symmetry is not inline and the proportions are not great.
Score – [3.0 ~ 5.9]
With this face analysis score, the results determine an average face because the facial symmetry is almost there. This group is the general population.
Score – [6.0 ~ 8.9]
With this face analysis score, the results may determine a very beautiful and attractive face because the symmetry is close to perfect.
Score – [9.0 ~ 10]
With this face analysis score, the results are unrealistic because you may be super beautiful or your photo is already retouched.
The Angle of the Face and Score Variations
The variation of the face score generally has to do with the angle at which the photo is taken and the pose of the face. Uploading the portrait photo with the person looking straight into the camera is necessary because the calculations need to be accurate. The Rule-of-fifth and Rule-of-third is formulated based on looking straight onto the face so keep that in mind during the uploading phase.
