A novel separating strategy for face hallucination

L Liu, W Li, S Tang, W Gong - 2012 19th IEEE International …, 2012 - ieeexplore.ieee.org
A novel separating strategy is proposed for resolving single face hallucination problem
when given an input low resolution face image. First, a local patch-based …

Effective two‐step method for face hallucination based on sparse compensation on over‐complete patches

MN Haju Mohamed, Y Lu, F Lv - IET Image Processing, 2013 - Wiley Online Library
Sparse representation has been successfully applied to image d using low‐and high‐
resolution training face images based on sparse representation. In this study, the sparse …

A new two-step face hallucination through block of coefficients

HMM Naleer, Y Lu, HMM Naleer - 2012 IEEE International …, 2012 - ieeexplore.ieee.org
We introduce a two-step face hallucination frame work as one of classifying among sparse
residual compensation model. In the first step, the optimal coefficients of the interpolated …
