Residual-in-Residual Dense Block (RRDB)
Neural block architecture introduced in ESRGAN combining residual connections and dense connections to facilitate training of very deep networks. Allows better information flow and efficient feature reuse.
Fractional Upsampling
Resolution enhancement technique using convolutions with fractional stride (stride < 1) to interpolate pixels in a learnable manner. Enables end-to-end learning of the upsampling process rather than using fixed methods like bicubic.
Real-ESRGAN
Extension of ESRGAN specifically designed for super-resolution of real-world images with complex and unknown degradations. Introduces learning with synthetic noise and an improved architecture to handle real artifacts.
GAN Prior
Use of a pre-trained GAN as latent space to constrain super-resolution to produce images belonging to the distribution of natural images. Allows generation of plausible details even with very high upscaling factors.
FaceGAN SR
Specialized application of GANs for super-resolution of human faces, using specific architectures and losses adapted to facial features. Combines semantic face analysis with super-resolution to preserve identity and expressions.
