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:
“When my face turned toward his,
I averted it
and looked at my feet.
When my ears clamored
to hear his talk,
I stopped them.
When my cheeks broke out
in sweat and goosebumps,
I covered them with my hands.
But Friends,
when the seams of my bodice
burst in a hundred places,
what could I do?”
—Amaru (c. seventh century A.D.)
