Parameters ---------- im_true : ndarray of int Ground-truth label image, same shape as im_test. im_test : ndarray of int Test image. ignore_labels : sequence of int, optional Labels to ignore. Any part of the true image labeled with any of these values will not be counted in the score. normalize : bool Determines if the contingency table is normalized by pixel count. sparse_type : {"matrix", "array"}, optional The return type of `cont`, either `scipy.sparse.csr_array` or `scipy.sparse.csr_matrix` (default). Returns ------- cont : scipy.sparse.csr_matrix or scipy.sparse.csr_array A contingency table. `cont[i, j]` will equal the number of voxels labeled `i` in `im_true` and `j` in `im_test`. Depending on `sparse_type`, this can be returned as a `scipy.sparse.csr_array`.
