Signature

def moments_hu ( nu )

Calculate Hu's set of image moments (2D-only).

Note that this set of moments is proved to be translation, scale and rotation invariant.

nu : (M, M) array: Normalized central image moments, where M must be >= 4.

image = np.zeros((20, 20), dtype=np.float64)
image[13:17, 13:17] = 0.5
image[10:12, 10:12] = 1

✓

mu = moments_central(image)
nu = moments_normalized(mu)
np.round(moments_hu(nu), 4)  # doctest: +FLOAT_CMP
