11/4/2005: Angry owl

mickja1 · 11-04-2005, 02:56 PM

On a close-up view, you can see an angry male owl. But further back, the face changes expression and even genders! If you squint, blink, or defocus, an angry male owl should substitute for the face of a neutral female owl.

This impressive illusion created by Dr. Aude Oliva and Dr. Philippe Schyns, illustrates the ability of the visual system to separate information coming from different spatial frequency channels. In the image, high Spatial Frequencies (HSF) represent a male owl, w69, 243-ith an angry facial expression, mixed with the low spatial frequency information from the face of a happy female owl.

Get a real job.
