Constructing adjacency graph from the segmentation image and tracking cells/nuclei in consecutive frames using adjacency graph node features. Color of nodes denote the label/track of the cell/nuclei. Initially, random labels are assigned for each node in the adjacency graph. For T + 1 frame, after node matching for time T, track IDs are assigned to each node in T + 1.
