Super-Resolution and Image Upscaling Techniques

AI-generated images often require post-processing enhancements, particularly when initial outputs have limited resolution. Super-resolution techniques use convolutional networks to refine pixel-level details and improve image sharpness.

Common AI-driven upscaling methods include:

  • GAN-Based Super-Resolution – Uses adversarial training to generate fine details while preserving realism. Example: Enhanced Super-Resolution GAN (ESRGAN).
  • Diffusion-Based Super-Resolution – Applies diffusion models to refine noisy low-resolution images, progressively reconstructing details at higher scales.
  • Fourier and Wavelet Transforms – Used in hybrid models to enhance frequency-domain information, reducing pixelation and improving texture continuity.
