Apparently so:

"Our approach is based on the observation that patches in a natural
image tend to redundantly recur many times inside the image, both within
the same scale, as well as across different scales. Recurrence of
patches within the same image scale (at subpixel misalignments) gives
rise to the classical super-resolution, whereas recurrence of patches
across different scales of the same image gives rise to example-based
super-resolution. Our approach attempts to recover at each pixel its
best possible resolution increase based on its patch redundancy within
and across scales."

Really cool.
