I have a question about this repo:

Should be 2 folders have similar image resolution?
If not, should we resize it by PIL or torch transforms resize? Thank you

mseitzer commented 3 years ago

The folders do not have to have the same resolution (but each image in each folder should have the same resolution)
The code automatically resizes images to the size required by the network.

In general, image resizing and FID is a tricky topic, see https://arxiv.org/abs/2104.11222.

Thank you so much for your reply.

I do not know that if my data_folder_1 has all PNG images and data_folder_2 has all JPG images, does the score make sense? Because I know that the value of pixels in the same images with different extension will be different. And one more question, I have folderA with all frontal faces while folderB is original FFHQ with many poses, genders,... Could we also calculate FID value between them?
