In particular, if given an array of coordinates of shape (Npoints, Ndim), it will remove repeated points. Parameters ---------- ar : 2-D ndarray The input array. Returns ------- ar_out : 2-D ndarray A copy of the input array with repeated rows removed. Raises ------ ValueError : if `ar` is not two-dimensional. Notes ----- The function will generate a copy of `ar` if it is not C-contiguous, which will negatively affect performance for large input arrays. Examples -------- >>> ar = np.array([[1, 0, 1], ... [0, 1, 0], ... [1, 0, 1]], np.uint8) >>> unique_rows(ar) array([[0, 1, 0], [1, 0, 1]], dtype=uint8) z2unique_rows() only makes sense for 2D arrays, got z|ST)Z return_index)ndim ValueErrornpZascontiguousarrayviewitemsizeshapeunique)arZ ar_row_view_Zunique_row_indicesZar_outr E/var/www/html/venv/lib/python3.8/site-packages/skimage/util/unique.py unique_rowss#  r)numpyrrr r r rs
