Face Deblurring Method and Device

A face deblurring device, characterized in comprising:

• a first acquisition unit, for acquiring a face image to be processed;
• a division unit, for aligning the face image to be processed onto a face mask, and performing grid division on the same;
• a matching unit, for matching each grid of the divided face image to be processed with a grid of a first grid dictionary, so as to obtain a plurality of blurred grids corresponding to each grid of the face image to be processed, wherein the first grid dictionary is obtained by dividing a first two-dimensional image library according to the face mask after alignment, and the first two-dimensional image library is a two-dimensional image library of blurred images constructed using a first three-dimensional image library obtained via a three-dimensional reconstruction method;
• a querying unit, for querying in a second grid dictionary a plurality of clear grids corresponding to the plurality of blurred grids on a one to one basis, according to the blurred grids, wherein the second grid dictionary is obtained by dividing a second two-dimensional image library according to the face mask after alignment, the second two-dimensional image library is a two-dimensional image library of clear images constructed using a second three-dimensional image library obtained via the three-dimensional reconstruction method, and the blurred images correspond to the clear images on a one to one basis;
• and
• a processing unit, for generating a clear image of the face image to be processed according to the queried clear grids.
