Webcomputation of homography. In the ﬁfth section, the result of our experiments is presented. The ﬁnal section concludes this paper and indicates future directions of our research. 2. HOMOGRAPHY The deﬁnition of a homography (or more generally projec-tivity) in [3] is an invertible mapping of points and lines on the projective plane P2. 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.
