Question about Data augmentation

[chaolistat]

In the paper, you mentioned adding noise to the training data and perturbeding the tone. May I know where the code for this part is? I couldn't find them. Thank you

Also, I would like to ask what the purpose of the following code is. I don't quite understand, thank you very much!

Hi,

1. Add noise on reference frame:

   DeepHDRVideo/models/hdr2E_model.py

   Line 128 in b968667

   self.perturb_low_expo_imgs(ldrs, expos)

   
   2.perturb the tone in:

   DeepHDRVideo/models/hdr2E_model.py

   Line 132 in b968667

   ldrs[self.ldr_mid] = noutils.pt_tone_ref_tone_augment(ldrs[self.ldr_mid], d=0.7)

2. The attached code generates a "new maximum value" for re-exposure. For example, if the value of new_anchor is 0.97, after the last two line of codes, values that larger than 0.97 will be cliped.

Thanks! But for 2. I still don't quite understand why a "new maximum value" is done.
And is the way the paper simulates over/ubder exposure consistent with real life?

Or could you tell me which part of the paper a "new maximum value" corresponds to? thanks
