On generating homography image pair

[toru34]

When you generate an image pair for homography estimation, do you apply transformation matrix to either just one side of the pair, or both?

I mean, the generated image pair is

• (original image, transformed image) ?
  Or
• (transformed image 1, transformed image 2) ?

I saw homography example images in the paper's appendix, and it seems each image of a pair is distorted to some degree.

I'd like to know whether my guess is correct.

Thanks.

Yes both images are transformed.
