About the degradation code

[YukinoshitaLove]

Dear authors, We noticed that you use the second-order degradation model from Real-ESRGAN [8] with ×4 down-sampling scale to generate the real-world degraded images. There appear to be several versions of this implementation available. Would it be possible for you to share the code used for generating the degradation? This would allow us to conduct a fair comparison. Alternatively, if your implementation of the degradation aligns with previous work, could you kindly provide the relevant link? We would greatly appreciate your help. Thank you!

Hi, for reproduce, we have included the Real-ESRGAN degraded images in the google drive. So you can directly test with our pre-degraded images.
