esrgansuperresolution

ESRGAN (Enhanced Super-Resolution GAN) aumenta la resolución de la foto del documento ×4, mejorando significativamente la calidad del face match en documentos con fotos de baja resolución o antiguas.

When to use

Aplicar cuando la foto extraída del documento tenga resolución menor a 100×100 píxeles o calidad BRISQUE > 50.

Instructions

  1. Instalar Real-ESRGAN: pip install realesrgan.
  2. Descargar modelo: RealESRGAN_x4plus.pth — https://github.com/xinntao/Real-ESRGAN.
  3. Inicializar: upsampler = RealESRGANer(scale=4, modelpath='RealESRGANx4plus.pth', tile=0, tilepad=10, prepad=0, half=True).
  4. Aplicar: output, = upsampler.enhance(facecrop, outscale=4).
  5. Redimensionar resultado al tamaño esperado por ArcFace (112×112).
  6. Usar solo cuando sea necesario para no añadir latencia innecesaria.

Notes

  • Repositorio: https://github.com/xinntao/Real-ESRGAN
  • half=True usa FP16 en GPU, reduciendo memoria y aumentando velocidad.
  • Benchmark: mejora el face match score ~0.05-0.15 en fotos de documentos de baja calidad.
