A new method of image mosaicking and its application to cultural heritage representation

This paper presents art original two-step procedure for estimating projecti ve transformations between pairs of images: first, the transformation betwe en the images is approximated as an affine transformation; second, this est imate is refined into that of a projective transformation. This strategy fo r matching projective views is computationally very efficient. The proposed method can be applied both to mosaicking of high resolution images of plan ar textured objects (e.g., frescoes and paintings), with subpixel accuracy, and to construction of panoramic images. Practical examples of mosaicking of cultural heritage imagery obtained by using the presented procedure are discussed in the paper.
