Face hallucination is super-resolution of face images, or clarifying the details of a face from a low-resolution image. The technique of sparse coding can be used. Because of the importance of face images in facial recognition systems and other applications, face hallucination has become an area of research.
Famous quotes containing the word face:
“The face we see was never young,
Nor could it ever have been old.
For he, to whom we had applied
Our shopman’s test of age and worth,
Was elemental when he died,
As he was ancient at his birth:”
—Edwin Arlington Robinson (1869–1935)
