An image can be condensed into an epitome, which captures the essence and statistically significant features of the image.  I created some matlab code based on Vincent Cheung’s examples that can be used for super-resolution. Here is an example result:

High resolution sample image

Epitome for sample image

The epitome itself may not be very interesting, however, it can be used to reconstruct details of a degraded image.
