The 2- and 3-fold covers of 7 points in the plane with respect to a particular scale parameter.
The multicover bifiltration is a two-parameter sequence of nested topological spaces derived from the covering of a finite set in a metric space by growing metric balls. It is a multidimensional extension of the offset filtration that captures density information about the underlying data set by filtering the points of the offsets at each index according to how many balls cover each point.[1] The multicover bifiltration has been an object of study within multidimensional persistent homology and topological data analysis.[2][3][4][5][6][7]
