Parameters

input_arr : array of int, shape (M[, ...]): The input label image.
input_vals : array of int, shape (K,): The values to map from.
output_vals : array, shape (K,): The values to map to.
out : array, same shape as `input_arr`: The output array. Will be created if not provided. It should have the same dtype as output_vals.

ski.util.map_array(
   input_arr=np.array([[0, 2, 2, 0], [3, 4, 5, 0]]),
   input_vals=np.array([1, 2, 3, 4, 6]),
   output_vals=np.array([6, 7, 8, 9, 10]),
