I mostly… can just barely see an ear above the train if I look, after being told to look there. I don’t think it’s “clear.” I also note that these are black-box attacks on humans which originated from ANNs; these are transferred attacks from eg a CNN.
Here, does this version help you see the cat? The ear is where you noted, and the left (from your perspective) eye is made up of the leftmost wiper blade plus a diagonal line at the top-left side of the left window that did not exist in the original image, and then the mouth is directly above the staircase at the top of the black horizontal stripe.=
To make that image, I converted both the left and right images to HSL, took the difference in luminance between the two, multiplied by 2.5, and applied that to the control image to yield the new “cat” image.
If you still don’t see it, below is an animated version of that transform alternating back and forth between 0x and 3x on that parameter.
The ‘cat’ here is the pair of white blobs on the crown of the train’s forehead, right? I have to say, no matter how I stare at it, it never looks ‘cat’ like to me. It only looks spider-like, a little.
Oh, that’s very surprising to me. I didn’t ever see the slightest hint of that left ear you draw there. You really see an ear there in the random bit of dark foliage? Huh.
Yeah, quite clearly. It looks like the ear of this cat, roughly. The eye shape is pretty similar too.
In addition, the tree above the train to the left turns into a blob with leopard spot patterns like this, and in the upper right foliage there is a fur-like texture with tiger stripes.
Anyway, I now have better drawing tools. Here is what I see, done by tracing over the picture in a separate layer:
I’m assuming you’re talking about our left, because you mentioned ‘dark foliage’. If so, that’s probably the most obvious part of the cat to me. But I find it much easier to see when I zoom in/enlarge the image, and I think I missed it entirely when I first saw the image (at 1x zoom). I suspect the screen you’re viewing it on can also make a difference; for me the ear becomes much more obvious when I turn the brightness up or the contrast down. (I’m tweaking the image rather than my monitor settings, but I reckon the effect is similar.)

I can definitely see the cat.

Original for reference:
To my eyes, the original image makes the cat clearer than your modifications.
What can I say, I’m a programmer, not an artist :)

In the discord I saw this dropped in at least 3 regulars immediately spotted the cat shape.
