WebHomography mapping is often exploited to remove perspective distortion in images and can be estimated using point correspondences of a known object (marker). We focus on scenarios with multiple markers placed on the same plane if their relative positions in the world are unknown, causing an indeterminate point correspondence. Existing … WebA method of point cloud coding using homography transform sends the homography transform of the 3D patches, instead of the explicit projection values (such as bounding boxes and patch orientation, rotation).
