4.2 Analysis of The Wall Painting

The groundwork and pigments of the Bezeklik wall painting are given in Table. 3.
Using i1 (made by Gretag Macbeth), we measured the spectrum characteristic of the
groundwork and pigments for gypsum, lime, vermilion, yellow ocher, azurite,
malachite, and the carbon obtained by marketing now. The color tone changes by
roughness of pigments. If pigments fine the color brightness grew stronger.

4.3 Reconstruction of The Wall Painting

For reconstruction of the wall painting, we consider a positional matching for
fragments of the wall painting (drawing, photographic image in the cave and at
museums) which are exist. (Fig.9.) Since the wall painting of the cave No. 4 is very
similar to one of the cave No. 9, characters in wall painting are also similar. Although
the wall painting of the cave No. 9 do not exist now, the facsimile, i.e. drawing, of it
is exist. Using digital high vision broad casting, we consider a zoom of an arbitrary
position on the reconstructed wall painting, thus a resolution is 7,000 x 7,000 pixels.
A digital reconstruction procedure of the cave No. 4 is as follows.
