Have you ever seen a portrait where the face or eyes appear to follow your every movement? These are popular decorations at haunted houses that are typically based on the hollow face illusion. In this illusion your brain is tricked into perceiving a concave face (i.e. hollow or caved-in) as actually standing out like normal face.
Inspired by creepy face following portraits, I decided to put a modern spin on the classic illusion by using real-time face detection. You can see from the video above and the photo below the project I created using a Raspberry Pi and camera running code based on openFrameworks and OpenCV. Follow this guide to learn how I built this creepy face tracking portrait!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
