Homographies were originally introduced to study shifts in perspective, and they have enabled people to better understand how images change when we look at them from a different perspective.
WebActually what it is doing is finding the transformation of the various points comparing the two frames. The points are chosen either randomly or based on some defined feature set, and are matched in the second frame. If their is correct match for the point, the points are joined to form homography matrix. In the field of computer vision, any two images of the same planar surface in space are related by a homography (assuming a pinhole camera model). This has many practical applications, such as image rectification, image registration, or camera motion—rotation and translation—between two images. Once camera resectioning has been done from an estimated homography matrix, this inform…
