Some problem about calcu_PSNR?

[C-water]

Hello,
In the project, the formula for calculating PSNR is as follows:
cal_psnr(HR_left[:,:,:,64:], SR_left[:,:,:,64:])

What does 64 represent?

Thank you.

Hi @chenquan-hdu, thanks for your interest in our work. For pair comparison with StereoSR, we follow its evaluation protocol and crop 64 pixels before calculating PSNR scores.

Thank you very much.
