Cell Tracking Accuracy Measurement Based on Comparison of Acyclic Oriented Graphs
Fig 2
An example of calculating the AOGM measure for a reference graph (upper left) formed of circular vertices and black edges and a computed graph (upper right) formed of rectangular vertices and dark pink edges.
In both graphs, the vertical axis represents the temporal domain and the horizontal axis represents the spatial domain (i.e., each vertex has a certain spatial extent). The AOGM measure is the weighted sum of the following quantities (bottom): the number of splits (NS = 5, black asterisks in pink-white rectangles) computed as the difference between the number of true positive vertices (20 green circles) and the number of white and pink-white rectangles containing at least one green circle (15), the number of false negative vertices (FN = 5, white circles with the black plus sign), the number of false positive vertices (FP = 3, white rectangles with the black cross), the number of redundant edges (ED = 1, black cross), the number of missing edges (EA = 16, small red circles), and finally the number of edges with wrong semantics (EC = 2, small blue circles).
