如果可能的话，我试图弄清楚如何在没有"if"条件的情况下使"z"轴对于 2D 和 3D 输入可选。因此，如果输入是 2D，它将忽略 z 轴。如果输入为 3D，则需要 z 值。任何帮助或建议将不胜感激。
def grey_closing(matrix, x=2, y=2, z=1):
matrix = ndimage.grey_opening(matrix, structure=np.ones((x,y,z)))
return matrix
test_result_aug_2 = grey_closing(test_result_aug_2)
这是我得到的错误：
RuntimeError Traceback (most recent call last)

也许：
structure_shape = (x, y, z)[:matrix.ndim]
structure = np.ones(structure_shape)
因此，如果matrix是 2D 的，则忽略z
