Image Segmentation by Edge Partitioning over a Nonsubmodular Markov Random Field

Algorithm 1

Minimizing edge partition.
()   Estimate image label state with the -means algorithm on pixels, .
()   Estimate and by the -means algorithm minimization of (4)
without the labeling constraint of (2).
()    Estimate the image label state using the QPBOI--expansion.
 (keep and constant)
()    Estimate and from the image label state .
()   If and are unchanged, terminate.
Else, repeat steps 3 and 4.
