do not have to impose the BPV term (namely,
γ
= 0). These parameters are fine
tuned empirically and adjusted manually. An automatic process to estimate the
parameters could be further studied in the future [46].
This model can be applied to various cases. Another experimental result can
be seen in Figure 10. The original segmentation result is far from satisfactory
(Figure 10b) because the stronger image details stop the propagation easily. In
this case, the introduction of color and texture into the speed term makes the
result closer to the user's expectation. We introduced a block color histogram and
