Which interpolation order in
scipy.ndimage.zoom uses nearest neighbor interpolation?Which interpolation order in scipy.ndimage.zoom uses nearest neighbor interpolation?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Recall interpolation orders in scipy.ndimage.zoom
Order 0 corresponds to nearest neighbor interpolation, which picks the closest pixel value.Step 2: Match order to interpolation type
Order 1 is linear, order 3 is cubic, and order 5 is higher-order spline interpolation.Final Answer:
order=0 -> Option BQuick Check:
Nearest neighbor = order 0 [OK]
Quick Trick: Nearest neighbor interpolation uses order=0 [OK]
Common Mistakes:
- Confusing order=1 (linear) with nearest neighbor
- Assuming higher order means nearest neighbor
- Using order=3 for nearest neighbor
