Abstract:
This paper compares the original implementation of the
trilateral filter with two proposed speed improvements. One is using
simple look-up-tables, and leads to exactly the same results as the
original filter. The other technique is using a novel way of truncating the
look-up-table to a user specified required accuracy. Here, results differ
from those of the original filter, but to a very minor extent. The paper
shows that measured speed improvements of this second technique are
in the order of several magnitudes, compared to the original or LUT
trilateral filter.
