Different Performance Measures

Example image to illustrate different performance measures. The left image shows two color coded document images. A pixel correspondence graph obtained from these images is shown on the right side. The nodes corresponding to the ground-truth segments are labeled 1-7, whereas the nodes in the segmented image are labeled a-i. Only significant edges are shown in the pixel correspondence graph. Based on the definitions given in Section II-C, the values of each performance measure for this example are given on the right side of the graph.
