3.5 Other nip features useful for reflectograms

You can use nip's general image processing facilities to play around with reflectogram mosaics. You can make false-colour images of your reflectograms, blend them with visible images or X-rays, search them for edges, and so on. See §2 for some examples.

There are also some first order mosaic functions: Mosaic_affine=>Left_right and Mosaic_affine=>Top_bottom. These functions automatically rotate and scale the right-hand image in a join. They are useful for assembling X-ray mosaics, and for fixing very difficult joins in reflectogram images. These functions work the same way as the Mosaic_translate functions except that you will need to define two tie-points on each image.

You can mosaic images of any numeric type: 16-bit integer images are handy for mosaicing X-ray images, for example.
