Web17 jun. 2024 · All these studies chose the four-point homography parameterization because the homography matrix H mixes the rotation, translation, scaling, and shear components of the homography transformation. The rotation and shear components tend to have a much smaller magnitude than the translation component.

WebThe homography maps a coordinate on a plane into another one so you actually HAVE to apply it to every single pixel (x' ; y' ; 1) = H (x ; y ; 1) where H is your 3x3 homography matrix. Doing this you'll get the new image (plus some black areas), simply iterate the equation for every pixel in the image.

Historically, the concept of homography had been introduced to understand, explain and study visual perspective, and, specifically, the difference in appearance of two plane objects viewed from different points of view.
