Comparison of different super-resolution techniques applied to the same HMI/SDO magnetogram. Panels (a) and (b) represent the ground truth and the degraded input image, respectively. The next images display the results of different methods: (c) latent diffusion model with residuals, (d) latent diffusion model without residuals, (e) palette with residuals, (f) palette without residuals (Saharia et al. 2021a), (g) Enhance model (Díaz Baso & Asensio Ramos 2018), and (h) progressive model (Rahman et al. 2020). This visual comparison highlights the impact of the LDM technique with residuals which shows fine-scale details with respect to the other reconstructions.
