GCGraph.
set_sink_nodes
(sink_nodes)[source]¶ Set multiple sink nodes and compute their t-weights.
Parameters: sink_nodes : sequence of integers
Declare the sink nodes via their ids.
Raises: ValueError
If a passed node id does not refer to any node of the graph (i.e. it is either higher than the initially set number of nodes or lower than zero).
Notes
It does not get checked if one of the supplied sink-nodes already has a weight assigned (e.g. by passing it to
set_source_nodes
). This can occur when the foreground- and background-markers cover the same region. In this case the order of setting the terminal nodes can affect the graph and therefore the graph-cut result.
