MS-SSIM Finetuning

[rezafuru]

Hi,

By my understanding, most work train PSNR and MS-SSIM optimized models separately. Hence, I was wondering whether there is any reason for fine-tuning an MSE trained model with MS-SSIM rather than using MS-SSIM as an objective on a newly initialized model.

Did you find better results with the finetuning approach, or did you want to save on train time by re-using the PSNR optimized weights?
