medpy.graphcut.graph.Graph.set_source_nodes

Graph.set_source_nodes(source_nodes)

Set the source nodes and compute their t-weights.

Parameters:

source_nodes : sequence of integers

Declare the source nodes via their ids.

Notes

It does not get checked if one of the supplied source-nodes already has a weight assigned (e.g. by passing it to set_sink_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.
