摘要

In learning-based face super-resolution algorithms, the traditional residue compensation methods are based on neighbor patches, which contain search steps with a large amount of computation and unsatisfied results. In order to improve the residue compensation step, a general residue compensation framework based on content similarity and linear combination of image patches is presented. The residue compensation framework directly uses the same content patches of the same position in the training set without searching step to compute the residue face. Different reconstruction methods can be used in the global reconstruction steps which were mentioned in this framework, thereby it has the general characteristic. Experimental results illustrate that the residue compensation method under the proposed framework can better recover the face image details, compared with the method of neighbor embedding based on residue compensation.
