Next, a graph is constructed with weighted edges on the energy function and is optimized with the graph cut algorithm. ...
As a result, the method combines the advantages of the level set method and graph cut algorithm, i.e., "topological" invariance and computational efficiency. ...
Based on the number of terminals, the graph cut could be classified into two groups: classical two-label graph cut and multilabel graph cut. ...

Optimization with graph cuts became very popular in recent years. While exact optimization is possible in a few cases, many useful energy functions are NP hard to optimize. ...
Two move-making algorithms based on graph cuts are in wide use, namely the swap and expansion. Both of these moves are binary in nature, that is they give each pixel a choice of only two labels. ...
