Aug 6th, 2017: Gabor Patches

Hey, whatchu lookin’ at?

Nope, it’s two concentric circles.

You want just one?

You can’t handle just one.

The secret is Gabor patches.

Quote:

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.

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

Yarr.

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!
