Question about how to create low-resolution images from high-resolution images to run on UniRes about unires HOT 1 OPEN

Hello @wendy-xiaozong ,

Appologies it took me some time to get back to you on this.

I have now added a demo notebook that shows how to apply the forward model of UniRes to generate a degrated, low-res image and perform reconstructions (i.e., the generation of high-res images):

https://github.com/brudfors/UniRes/blob/master/demos/demo_forward_model.ipynb

The notebook visualises results along the way and computes the SSIM between two types of reconstruction: trilinear resampling and super-resolution with the UniRes algorithm. In terms of SSIM, UniRes performs better than trilinear resampling.

I would look at the demo script for generating your low-res images, as this is the model that UniRes assumes for how a low-res image is generated (its 'generative model'). Keep in mind that you might want to set eo_scl = 0 and std_noise = 0 if you simply want to create low-res scans, without additional degradations.
