Fig. 6

Illustration of FU detection using the IWB method for a coherence network with the coherence matrix shown in Table 1. Three basins are represented by a green diamond, red star, and magenta up-triangle, respectively. Blue squares represent vertices that have at least one significant edge in the queue connected to a labelled vertex. The edges in queue and their values are listed (in descending order) on the right for each step. The new inserted edges are indicated by bold text, e.g., “e-i” which appears at S7. S14 illustrates the vertex positions in the 2D space
