Some confusion about details of homography matrix.

[Estrellama]

Hello, I really appreciate your work, but there are some issues regarding the details.

I'm confused about how the homography matrix is calculated in the panorama image generation task of your work. What does the phrase "pixel-to-pixel correspondences are available, such as perspective crops from panorama" mean in the abstract section of the paper? Are you saying that all adjacent image pairs in the panoramic image share the same homography matrix? As far as I know, the homography matrix for each image pair needs to be recalculated.

Thank you for your time and for considering my questions. Looking forward to your response. Best regards, Enhui Ma
