tumourkit.postprocessing.merge_cells.create_id_map

tumourkit.postprocessing.merge_cells.create_id_map() → Tuple[Callable[[ndarray], ndarray], Dict[int, Tuple[int, int]]]

Creates an index mapping function and its inverse mapping based on a unique difference per pair. The index mapping function f is defined as f(x) = x^5, ensuring that the difference between function values for each pair of indices is unique.

Returns:

A tuple containing the index mapping function f and the inverse mapping of the differences.

Return type:

Tuple[Callable[[np.ndarray], np.ndarray], Dict[int, Tuple[int, int]]]
