For addressing the problem of hallucinating a higher resolution face given a low resolution input face, the goal of face hallucination aim should be to produce high resolution images with fidelity from low-resolution ones. Face hallucination is a technique of domain-specific super-resolution problem having goal to generate high-resolution images from low-resolution inputs, which finds numerous vision applications. Since a LR image can be made from a HR image by a linear convolution process with

In this paper, we study face hallucination which is the process of synthesizing a high-resolution face image from an input LR image, with the help of a large collection of other HR face images.
