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 system
s and other applications, face hallucination has become an area of research.
Super-resolution
Super-resolution are techniques that enhance the resolution of an imaging system. Some SR techniques break the diffraction-limit of systems, while other SR techniques improve over the resolution of digital imaging sensor....

Sparse coding
The sparse code is a kind of neural code in which each item is encoded by the strong activation of a relatively small set of neurons. For each item to be encoded, this is a different subset of all available neurons....

Face
The face is a central sense organ complex, for those animals that have one, normally on the ventral surface of the head, and can, depending on the definition in the human case, include the hair, forehead, eyebrow, eyelashes, eyes, nose, ears, cheeks, mouth, lips, philtrum, temple, teeth, skin, and...
