SciPy - Image Processing (scipy.ndimage)

What will be the effect on the image array after applying a median filter with size=3 using SciPy?

AThe image size will double

BThe image will become blurred with Gaussian noise

CThe image colors will invert

DThe image will have reduced salt-and-pepper noise

Step-by-Step Solution

Solution:

Step 1: Understand median filter effect
Median filters remove salt-and-pepper noise by replacing each pixel with the median of neighbors.
Step 2: Evaluate options
Median filter does not blur with Gaussian noise, invert colors, or change image size.
Final Answer:
The image will have reduced salt-and-pepper noise -> Option D
Quick Check:
Median filter effect = Noise reduction (salt-and-pepper) [OK]

Quick Trick: Median filter removes salt-and-pepper noise [OK]
