Abstract
The present application discloses a method for recovering a face image based on semantic features, which includes obtaining a to-be-recovered face image; inputting the to-be-recovered face image into a recovery model trained to obtain a recovered face image; the recovery model includes: an encoder, configured for generating low-quality face semantic features based on the to-be-recovered face image; a reference image generator, configured for generating a plurality of high-quality face reference images by inputting random noise based on the low-quality face semantic features; a feature transfer, configured for constructing a face component feature dictionary based on the plurality of high-quality face reference images, and transferring high-quality component features in the face component feature dictionary to the low-quality face semantic features to obtain high-quality face semantic features; and a decoder, configured for generating the recovered face image based on the high-quality face semantic features.
