On: Sir, there's a cat in your mirror dimension

[toast0]

I'm a little bit slow with all this stuff, can somebody confirm this is the process:

a) take photo of woman and photo of cat

b) DCT cat into the frequency domain

c) composite the frequency domain cat into the visual image of the woman

d) if you DCT the composite image, you get the cat back? (or more specifically, you get the visual cat and the frequency domain woman composited; but the visual cat dominates)

[woopsn → toast0]

Yep, that's it.

[wwilim → woopsn]

Does that mean DCT(DCT(image)) == image?

[jcul → wwilim]

Yeah, that's it.
