A fast and reliable planar registration method with applications to document stitching
Maurizio Pilu, Francesco Isgrò · 2002
This paper presents a fast and extremely robust feature-based method for planar registration of partly overlapping images that uses a twostage robust tting approach comprising a fast estimation of a transformation hypothesis (that we show is highly likely to be correct) followed by a con rmation and re nement stage. The method is particularly suited for automatic stitching of oversize documents scanned in two or more parts. We show simulations, also supported by practical experiments, that prove both the robustness and computational eAEciency of the approach.
