SciPy - Image Processing (scipy.ndimage)
Which of the following is the correct syntax to zoom an image array
img by a factor of 1.5 using scipy.ndimage.zoom?Which of the following is the correct syntax to zoom an image array img by a factor of 1.5 using scipy.ndimage.zoom?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recall zoom function signature
Thescipy.ndimage.zoomfunction accepts the zoom factor as the second positional argument without needing the parameter name.Step 2: Check each option
scipy.ndimage.zoom(img, 1.5) correctly uses the zoom factor as a positional argument. scipy.ndimage.zoom(img, zoom=1.5) is invalid because the function does not have a named parameter 'zoom'. Options C and D use incorrect parameter names.Final Answer:
scipy.ndimage.zoom(img, 1.5) -> Option AQuick Check:
Zoom factor passed as positional argument [OK]
Quick Trick: Pass zoom factor as second positional argument [OK]
Common Mistakes:
- Using wrong parameter names
- Omitting parameter name causing confusion
- Using scale or factor instead of zoom
