SciPy - Image Processing (scipy.ndimage)

The following code is intended to perform erosion on a binary image, but it raises an error. What is the problem?

import numpy as np
from scipy.ndimage import erosion

image = np.array([[1, 1, 0],
                  [1, 0, 0],
                  [0, 0, 1]])

result = erosion(image)
print(result)

AThe function 'erosion' does not exist in scipy.ndimage; use 'binary_erosion' instead.

BThe input image must be float type, not int.

CThe image array shape is invalid for erosion.

DThe print statement syntax is incorrect.

Step-by-Step Solution

Solution:

Step 1: Check function availability
Scipy.ndimage does not have a function named 'erosion'; the correct function is 'binary_erosion'.
Step 2: Correct the import and usage
Replace 'from scipy.ndimage import erosion' with 'from scipy.ndimage import binary_erosion' and call 'binary_erosion(image)'.
Final Answer:
The function 'erosion' does not exist in scipy.ndimage; use 'binary_erosion' instead. -> Option A
Quick Check:
Use binary_erosion, not erosion [OK]

Quick Trick: Use binary_erosion, not erosion function [OK]

Common Mistakes:

Trying to import non-existent 'erosion'
Ignoring error messages
Assuming all morphological functions have simple names
