About the Tog13 datasets

[syujung]

Dear guanying， The file (TOG13 dataset) you provided in google drive already contains the hdr images , I want to know if those hdr images are predictd by the network you proposed in paper ？

Hi, those HDR images are results of the Kalantari 13's method.

Ok, I noted you used the pre-alignment when testing on TOG13 datasets，and you do not use pre-alignment when testing on datasets you proposed ，I wonder if the pre-alignment is necessary for testing on TOG13 datasets？ And if the algorithm is robust to handle the global motion，do we need to prealign the images before we put images into the network ？

Thank you again for your patient reply！ Your reply helped me a lot！

We do not pre-align when testing on our dataset because we are evaluating the robustness to global motion. I think global image alignment is helpful as it reduce the difficulty in HDR fusion.
