Abstracting data from ICE RRS feed

  • Question

  • This is an excellent tool - thank you.

    I am studying C19th print techniques, by scanning large impressions on paper at high resolution, 1200 ppi.

    ICE takes the overlapping scans, aligns them, then stitches them. If the alignment is easy, e.g. a linear sequence of images, the stitching seems pixel perfect. Indeed the overlap area seems to have increased resolution by averaging.  If alignment is not easy, e.g. a checkerboard, the averaging produces a fuzzy area in the overlap.

    I wish to identify differences between nearly identical impressions in order to reveal the progressive changes added by the artist.  Instead of creating an average matrix from the 2 aligned image matrices, is it possible to extract the difference matrix +/- after the alignment stage?
