We have tested our LBP on totally 34 patches and the
results are listed in Fig.1 and 2 We have tested our element
decomposition algorithm on the same 15 Manga characters
to understand its performance. Fig. 3 and 4 show all 15 of
the decomposition results. Fig. 5 and 6 show the results
of applying our intuitive Manga patch vectorization and
manipulation methods for several Manga objects drawn by
different artists to show the effectiveness of our algorithm.
At the same time, we also show the comparison with
the vectorization results generated by Adobe illustrator.
Figure 7 shows the results of context completion after a user
drew scribbles and the semantic components can then be
manipulated individually and locally for interesting effects.
Figure 8 shows more interesting composition of Manga
objects.
