[Solved] The following code attempts to apply the Laplace filter but raises an error. What is the mistake? from scipy import ndimage img = [[1, 2, 3], [4, 5, 6], [7, 8]] laplace_img = ndimage.laplace(img) | SciPy

SciPy - Image Processing (scipy.ndimage)

The following code attempts to apply the Laplace filter but raises an error. What is the mistake?

from scipy import ndimage
img = [[1, 2, 3], [4, 5, 6], [7, 8]]
laplace_img = ndimage.laplace(img)

Andimage.laplace does not exist in SciPy

BLaplace filter requires axis parameter

CThe image must be grayscale

DThe input image must be a NumPy array, not a list

Step-by-Step Solution

Solution:

Step 1: Check input type for ndimage filters
ndimage functions require NumPy arrays, not Python lists, for image input.
Step 2: Identify error cause
Passing a list causes a TypeError because ndimage.laplace expects an array.
Final Answer:
The input image must be a NumPy array, not a list -> Option D
Quick Check:
ndimage needs np.array input [OK]

Quick Trick: Convert lists to np.array before filtering [OK]
