Poor correspondence of cell centroids. Using the pairwise distances between cell centroids would result in mismatched cells; as a result, this motivates the use of the union over intersection to compute the cost matrix. Here, the color code is based on the ground truth correspondence while the edges highlight the misassignments based on cell centroids. The image is taken from cell labels from the ovules dataset [31]
