ideal test_patch size?

Thank you so much for this amazing work. And congratulations on the research paper accepted at CVPR.

I want to evaluate your models on the Set 5 dataset. However, when I ran the model (4X) with the default test_patch argument [1,1], the results were images with total noise. I don't know for sure what's the issue, but I tried changing the default test_patch argument to [2,2] and got the following results. It is a little better than totally noisy images. Changing test_patch size is affecting the resulting super-resolution image, so what should be the ideal value for the test_patch parameter?

img_001
img_002
img_003
img_004
img_005

As you can see the results do not look good. What am I missing here?

It will mean a lot if I can get any leads about what can be going wrong here.

Thank you in advance!

Artefacts using pre-trained weights

Hi,

Thanks for the code.

I tried to test the pre-trained models on the Set5 dataset you provided running:
python main.py --phase 'test' --test_data_path 'Set5/LR/X4/imgs' --test_label_path 'Set5/HR' --test_ckpt_pat ./upsampling_network_x4 --factor 4.

However, the results have grid artefacts like this one:

I am using TensorFlow 1.13 like mentionned in the requirements.

Is there something I missed in the params ?

Thanks,
Charles
