"Face Hallucination"

For those that scoff at television crime dramas when they create high-res images from grainy surveillance video:

"In this paper, we study face hallucination, or synthesizing a high-resolution face image from an input low-resolution image, with the help of a large collection of other high-resolution face images. Our theoretical contribution is a two-step statistical modelling approach that integrates both a global parametric model and a local nonparametric model. Our practical contribution is a robust warping algorithm to align the low-resolution face images to obtain good hallucination results. The effectiveness of our approach is demonstrated by extensive experiments with high-quality hallucinated face images with no manual alignment."
