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:
“She leaned far out on the window-sill,
And shook it forth with a royal will.
“Shoot, if you must, this old gray head,
But spare your country’s flag,” she said.
A shade of sadness, a blush of shame,
Over the face of the leader came;”
—John Greenleaf Whittier (1807–1892)
