why only set pairwise once?

[s20163081161]

/* cost types /
using unary_t = UnaryTable<cost_t, simd_w>;
using pairwise_t = PairwiseTruncatedLinear<cost_t, simd_w>;
.......
/ construct pairwise costs */
pairwise = std::unique_ptr<pairwise_t>(new pairwise_t({1.0, 2.0}));
.....

for(luint_t n = 0; n < num_nodes; ++n)
mapmap.set_unary(n, unaries[n].get());
mapmap.set_pairwise(pairwise.get());

why only set pairwise once? what dose "new pairwise_t({1.0, 2.0})" mean ?

Look forward to your reply. Thanks!

Hi,

setting this only once means that all edges hare the same cost function. Parameters {1.0, 2.0} lead to the following cst function: c(l_1, l_2) = 1.0 * min(abs(l_1 - l_2), 2.0) as is seen in line135ff of the code.
