Aug 6th, 2017: Gabor Patches

[xoxoxoBruce]

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.

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.
