HyperFace — False Faces on Fabric

Repeated face-like patterns on fabric try to redirect a face detector towards decoys around the wearer.

Find the repeated eye-and-mouth arrangements on the illustrated shirt and enlarged fabric. The blue boxes suggest candidate regions a detector might consider; they are drawn annotations, not algorithm output.

The original pattern targeted OpenCV’s Viola–Jones Haar-cascade face detector. Face-like contrast on the fabric could trigger false positives. The proposed decoy effect exploits a system that prioritises a candidate face; a system that keeps multiple detections may still find the real face. Adding face candidates does not establish that identity matching has been defeated.
