Abstract
This paper details an unsupervised algorithm for image super-resolution 
based on a reaction-diffusion model. The diffusion is anisotropic, 
inspired by Perona-Malik diffusion. The reaction term favors 
compatibility with the low resolution input image. The implementation is 
simple and mainly relies on numerical schemes to approximate the 
required differential operators. The different possibilities present in 
the literature are analyzed and tested, leading to the choice of the 
best ones. Qualitative experiments illustrate the results on some images.
