easy📝 Conceptual Q2 of 15
SciPy - Image Processing (scipy.ndimage)
Which interpolation order in scipy.ndimage.zoom uses nearest neighbor interpolation?
Aorder=1
Border=0
Corder=3
Dorder=5
Step-by-Step Solution
Solution:
  1. Step 1: Recall interpolation orders in scipy.ndimage.zoom

    Order 0 corresponds to nearest neighbor interpolation, which picks the closest pixel value.
  2. Step 2: Match order to interpolation type

    Order 1 is linear, order 3 is cubic, and order 5 is higher-order spline interpolation.
  3. Final Answer:

    order=0 -> Option B
  4. Quick 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
