SciPy - Image Processing (scipy.ndimage)

Which of the following is the correct way to call scipy.ndimage.zoom to double the size of an image array img with linear interpolation?

Azoom(img, zoom=2, order=1)

Bzoom(img, scale=2, order=1)

Czoom(img, zoom=2, interpolation='linear')

Dzoom(img, factor=2, order=1)

Step-by-Step Solution

Solution:

Step 1: Check parameter names in scipy.ndimage.zoom
The correct parameter for resizing factor is zoom, not scale or factor.
Step 2: Check interpolation order
Order=1 means linear interpolation, which is correct. The parameter interpolation does not exist.
Final Answer:
zoom(img, zoom=2, order=1) -> Option A
Quick Check:
zoom param + order=1 for linear [OK]

Quick Trick: Use zoom= factor and order= interpolation level [OK]
