Does face detection work with beards, sunglasses, or eyeglasses?

When to use this

Use this reference when you need to understand how Displai’s audience analytics face detection performs with common facial accessories and features like beards, sunglasses, or eyeglasses.

Face detection compatibility

The Sightcorp face detection engine used by Displai is designed to be robust against common facial features and accessories.

Beards: Face detection works normally with beards of any length or style.

Eyeglasses (prescription glasses): Face detection works normally with eyeglasses.

Sunglasses: Face detection works with sunglasses, but sunglasses may reduce the accuracy of emotional classification. The darkened lenses obscure the eye region, which is a key input for emotion detection algorithms.

Technical context

Emotion detection relies heavily on analyzing the eye region and surrounding facial muscles. Sunglasses block visibility of these areas, which is why they can affect emotional classification while still allowing face detection to succeed.
