FWHR stands for Facial Width-to-Height Ratio. It is a measurement that quantifies the proportion of a person's face by dividing the bizygomatic width (the widest part of the face, typically across the cheekbones) by the upper facial height (the vertical distance from the top of the upper lip to the highest point of the eyelids or the mid-brow). 

This ratio provides a numerical representation of facial structure and its relative broadness.

Traditionally, FWHR can be measured manually using calipers on a physical photograph. However, Perfect Corp's AI technology automates this process. 

Our system analyzes an uploaded image, precisely detecting the face to measure the bizygomatic width (distance between the outer edges of the cheekbones) and the upper facial height (vertical distance from the upper lip to the brow line). 

These measurements are then used to calculate the FWHR accurately and instantly, removing human variability from the process.

The FWHR has been correlated with various biological and psychological traits. 

In aesthetic contexts, FWHR is sometimes considered a factor in overall facial harmony and balance, contributing to perceived attractiveness. Its significance lies in offering an objective measure that can be explored in relation to diverse human perceptions and attributes.

Perfect Corp's AI utilizes sophisticated algorithms trained on extensive datasets to ensure high accuracy in facial point detection. This technological foundation allows for consistent and reliable measurement of various facial attributes, moving beyond subjective assessment to objective, quantifiable data. 

The precision of our AI systems supports a wide range of applications, from personal aesthetic analysis to professional consultation.

By providing an accurate FWHR, our tool empowers users to explore the science behind facial balance and the subtle ways proportions can influence overall appearance.

Our advanced AI systems can also provide age estimation from photos, allowing users to explore "how old do I look" with objective analysis. 

This integrates seamlessly with other tools like virtual try-on for makeup and hairstyles, and cosmetic treatment simulations, providing a holistic platform for personalized aesthetic exploration. 

Understanding your FWHR can inform decisions in these areas, helping to achieve desired visual outcomes.

This integrated approach offers a more complete picture of facial characteristics, supporting both individual curiosity and professional applications in beauty and aesthetics.
