Image Segmentation by Edge Partitioning over a Nonsubmodular Markov Random Field

Figure 5

The segmentation evaluation (PRI, VoI, and BDE) versus threshold values is plotted for CtoR. Different threshold values give an optimal score for each segmentation evaluation approach. In contrast, the proposed EPartition is independent of the threshold values and finds the approximate optimal segmentation for all evaluation approaches.
