Witryna21 sie 2024 · Homography. A homography, is a matrix that maps a given set of points in one image to the corresponding set of points in another image. The homography is a 3x3 matrix that maps each point of the first image to the corresponding point of the second image. See below where H is the homography matrix being computed for … WitrynaThe former estimates multiple homographies computed from local geometries to align the input images, e.g., as-projective-as-possible (APAP) warping [5] .
