[Solved] Identify the error in the following code snippet that applies a Gaussian filter: import numpy as np from scipy.ndimage import gaussian_filter image = np.... | SciPy

SciPy - Image Processing (scipy.ndimage)

Identify the error in the following code snippet that applies a Gaussian filter:

import numpy as np
from scipy.ndimage import gaussian_filter

image = np.ones((5,5))
filtered = gaussian_filter(image, sigma='2')
print(filtered)

Agaussian_filter cannot be applied to numpy arrays

BThe array shape is invalid for gaussian_filter

CMissing import for numpy

Dsigma should be a number, not a string

Step-by-Step Solution

Solution:

Step 1: Check parameter types
The sigma parameter must be a numeric value (int or float), not a string.
Step 2: Identify the cause of error
Passing '2' as a string causes a type error when the filter tries to compute the blur.
Final Answer:
sigma should be a number, not a string -> Option D
Quick Check:
Numeric sigma required, string causes error [OK]

Quick Trick: Use numeric sigma, not string, to avoid errors [OK]
