Anyone knows a way to do a good "photoshop" high pass filter with jitter?

This is what i thought at first too, but the result have nothing similar.

i am trying to achieve high pass filter that turn the picture into that weird average greyscale thing.

i attach you a screenshot to show the difference. left is photoshop high pass filter, right up is original,

it's pretty straight forward, as explained in 

 article: "the High Pass filter is actually based on Low Pass - or Gaussian Blur. The trick with High Pass is to take the signal, Low Pass it, invert it, and then mix it back to the original signal."

ahh ok, never heard of this before.
