Face Symmetry Test

Face Symmetry Test is a web-based tool that uses artificial intelligence to analyze the symmetry of a human face from a single uploaded photograph. The core function is to evaluate how symmetrical a person’s facial features are by comparing seven predefined feature pairs: left and right eyes, left and right eyebrows, left and right ears, the nose (nasal symmetry), the mouth, the cheeks, and the jawline. Users take a frontal photo with neutral expression under even lighting, then upload it to the platform. The AI model processes the image, detects facial landmarks, and calculates a symmetry score for each feature pair as well as an overall facial symmetry percentage. The tool provides a visual overlay showing the midline of the face and highlights areas where asymmetry is detected, making the results easy to interpret. The primary use case is personal curiosity: individuals who want to check their own facial symmetry out of interest or for entertainment. It is also used by people researching facial aesthetics, such as makeup artists, model scouts, or photographers who need a quick, objective baseline of a subject’s face. The tool has a practical application in the beauty industry: before and after cosmetic procedures, clients can measure changes in symmetry objectively. For medical purposes, the tool can help patients and doctors monitor facial asymmetry caused by conditions like Bell’s palsy, dental issues, or trauma, though it is not a diagnostic device. The analysis focuses solely on static symmetry and does not measure dynamic movements or expressions. The AI works by first detecting the face’s bounding box and then aligning it to a standardized position. It then identifies 68 facial landmarks (based on the common 68-point model) and compares the distances and angles
