a depth edge can only composite by one type of pixel(FG or BG).

assumption is satisfied.
(A) A depth edge is invalid if both of its "far_flag"(BG) and
"near_flag"(FG) are True.
(B) If the depth edge is invalid, we need to do:
(1) Find the role("oridinal") of each pixel on the depth edge.
"-1" --> Its opposite pixels has smaller depth(near) than it.
It is a backgorund pixel.
"+1" --> Its opposite pixels has larger depth(far) than it.
It is a foregorund pixel.
"0" --> Some of opposite pixels has larger depth(far) than it,
and some has smaller pixel than it.
It is an ambiguous pixel.
(2) For each pixel "discont_node", check if its neigbhors' roles are consistent.
- If not, break the connection between the neighbor "ne_node" that has a role
different from "discont_node".
- If yes, remove all the role that are inconsistent to its neighbors "ne_node".
(3) Connected component analysis to re-identified those divided depth edge.
(C) Aggregate each connected part in "discont_graph" into "discont_ccs" (A.K.A. depth edge).
