Description:
A Dysample RealPLKSR 4x upscaling model that was trained with / handles jpg compression down to 70 on the Nomosv2 dataset, preserved DoF.
Based on the [4xmssim_realplksr_dysample_pretrain](https://github.com/Phhofm/models/releases/tag/4xmssim_realplksr_dysample_pretrain) I released 3 days ago.
This model affects / saturate colors, which can be counteracted a bit by using wavelet color fix, as used in these examples.
Added a static (3 256 256) onnx conversion, with fp32 and fully optimized. This can be used with chaiNNer, since the dysample pth file would be unsupported. (Removed other conversions like statis with 128 because they would produce different results, but static 256 gives the same result as using the pth file with neosr testscript.
