SciPy - Image Processing (scipy.ndimage)

What is the issue with this code?

from scipy.ndimage import gaussian_filter

img = [[5, 10], [15, 20]]
result = gaussian_filter(img, sigma=[1, 2])
print(result)

APassing sigma as a list is invalid; sigma must be a single float

BThe input image must be a numpy array, not a list

CThe gaussian_filter function does not accept 2D arrays

DThe print statement is missing parentheses

Step-by-Step Solution

Solution:

Step 1: Check input type
Gaussian filter requires numpy arrays, but img is a Python list.
Step 2: Sigma parameter
Sigma can be a scalar or sequence matching input dimensions, so sigma=[1,2] is valid.
Step 3: Print statement
Print statement syntax is correct in Python 3.
Final Answer:
Option B -> Option B
Quick Check:
Input must be numpy array, not list [OK]

Quick Trick: Input must be numpy array, not plain list [OK]
