Super-resolution of very low-resolution face images with a wavelet integrated, identity preserving, adversarial network

作者:

Highlights:

• The network minimizes a combination of loss functions to make a balance between distortion and perception.

• The method predicts wavelet coefficients to improve reconstruction of high-frequency components.

• The wavelet-enriched features are concatenated with original features as complementary information.

• The GAN framework is utilized to enhance the perceptual quality.

• An identity loss is aggregated to help the SR network preserve facial identity during hallucination.
