Hey, whatchu lookin’ at?

Nope, it’s two concentric circles.

Image

You want just one?

You can’t handle just one.

The secret is Gabor patches.

Gabor patches can be varied; the separation between the lines (the frequency) can be bigger or smaller, the lines can be angled, and more. Most importantly, you can change the phase: where the lines fall in the patch. Changing the phase means the lines get shifted parallel to their length. So a phase of, say, 0, means the brightest line is in the middle of the patch, and a phase of 0.5 shifts it so that the darkest line is in the middle.


They make straight lines look crooked too.

You’re getting sleepy… sleepy… sleepy…

From a bunch of concentric circles.

Can you imagine an animal with Gabor patches as camouflage? It would hurt just to look at them at all.

Would make a great addition to the standard ophthalmologist's torture tests.

Good. One thing that makes sense to an old lady. But my son will appreciate the rest of it!
