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:
“Come, gentle night, come, loving, black-browed night.
Give me my Romeo, and when I shall die,
Take him and cut him out in little stars
And he will make the face of heaven so fine
That all the world will be in love with night,
And pay no worship to the garish sun.”
—William Shakespeare (1564–1616)
