Homography in computer vision
Web5 apr. 2024 · Homography estimation is an important step in many computer vision problems. Recently, deep neural network methods have shown to be favorable for this problem when compared to traditional methods. However, these new methods do not consider dynamic content in input images.

Web14 feb. 2012 · Homography only works for planar scenes (ie: all of your points are coplanar). If that is the case then the homography is a projective transformation and it can be decomposed into its components. But if your scene isn't coplanar (which I think is the case from your description) then it's going to take a bit more work.
