popari.components.PopariDataset.remove_connectivity_artifacts

static PopariDataset.remove_connectivity_artifacts(sparse_distance_matrix, sparse_adjacency_matrix, threshold=94.5)

Remove artifacts in adjacency matrices produced by heuristic algorithms.

For example, when Delaunay triangulation is used to produce the adjacency matrix, some spots which are connected as a result may actually be far apart in Euclidean space.

Parameters:

• sparse_distance_matrix (csr_matrix)

• sparse_adjacency_matrix (csr_matrix)

• threshold (float)
