How Does AI Detect & Analyse Face Shape?

You might have wondered how the AI-Powered Face Shape Detector works, how the app is detecting and analysing my face shape so accurately, and gives an instant result.

Basically, all these web and mobile apps for face shape analyzers use advanced artificial intelligence (AI) and computer programs that are designed to mimic human thinking.

Once you upload an image or use the Live camera, the system will start studying the landmarks of your face. These landmarks are your eyes, nose, jawline, cheekbones, and forehead shape. These systems are highly trained in reading and analyzing all these landmarks.

The AI uses all these landmarks and measures the distances and angles between the jawline, forehead, cheekbones, etc, and determines the facial shape. You will get the result instantly in real time, because in the backend, these are functioning very fast and quickly within seconds.

If you are uploading an image, then you need to make sure that the image is clean and clear so that the system can easily find all the landmarks on your face. Side pose images, low-lighting images, and blur images can lead to poor results.

Using a live camera also needs some proactive actions. You are standing in front of the camera in a way that your face is clear and with proper lighting. Use a high-resolution camera to get a better quality image.
