I am trying to send coordinate of an image for point addition to another function but in the point_addition function, its unable to unpack the coordinates of point as x1 and y1

I am trying to send coordinate of an image for point addition to another function but in the point_addition function, its unable to unpack the coordinates of point as x1 and y1.
here is the code:

def point_addition(p1, p2, P):
x1, y1 = p1
x2, y2 = p2

``````# Replace with the actual equation of the HEC curve
h = lambda x: 0  # Replace with the actual polynomial h(x)
F = lambda x: (x**5 + 1184*x**3 + 1846*x**2 + 956*x + 560) % P

lam = (y2 - y1) / (x2 - x1)
x3 = (lam**2 - x1 - x2) % P
y3 = (lam * (x1 - x3) - y1) % P

return (x3, y3)
``````

def encrypt_image(image, P):
# Phase mask generation and masking process
phase_mask_1 = np.random.uniform(np.pi, 2*np.pi, size=image.shape[:-1] + (1,))
masked_image = image * np.exp(1j * phase_mask_1)

``````# Phase Truncated Fourier Transformation (PTFT)
ptft_image = np.abs(np.fft.fftshift(np.fft.fft2(masked_image, axes=(0, 1))))

# Scrambling using hyper elliptic curve (HEC)
scrambled_image = ptft_image.copy()

for i in range(image.shape[0]):
for j in range(image.shape[1]):
point_1 = scrambled_image[i, j]
point_2 = scrambled_image[(i + 1) % image.shape[0], (j + 1) % image.shape[1]]
image_array = np.array([point_1, point_2], dtype = np.float64)
scrambled_image[i, j] = point_addition(image_array[0], image_array[1], P)
``````
