BHI Small SISR Dataset

This is a small version of my BHI SISR Dataset, it consist of 12k 512x512 png training tiles.
The same way as BHI_mini, the focus of this dataset was to extract the high information density and good quality images from the dataset, together with deduplication.
This dataset contains more training tiles than BHI_mini, which is beneficial for medium and big networks, especially when pre-applying degradations for paired training for better degradation distribution.
For complex pre-applied degradation (many different types and strengths) or diffusion network, probably the standard BHI might give better results.

I provide two LR sets with this, x2 and x4, which have been downsampled with pillow bicubic. In the validation folder I also provide an Urban100 HR, x2 and x4 set which have been downsampled the same way.
