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:
“Nor now the long light on the sea—
And here face downward in the sun
To feel how swift how secretly
The shadow of the night comes on . . .”
—Archibald MacLeish (1892–1982)
