easy📝 Conceptual Q1 of 15
SciPy - Image Processing (scipy.ndimage)
What is the main effect of applying scipy.ndimage.rotate to a 2D image array?
AIt scales the image dimensions by a given factor
BIt rotates the image by a specified angle around its center
CIt flips the image horizontally
DIt applies a Gaussian blur to the image
Step-by-Step Solution
Solution:

  1. Step 1: Understand the function

    scipy.ndimage.rotate is designed to rotate an image array by a specified angle.

  2. Step 2: Effect on image

    The rotation is performed around the center of the image, changing the orientation but not scaling or flipping it.

  3. Final Answer:

    It rotates the image by a specified angle around its center -> Option B

  4. Quick Check:

    Rotation changes orientation, not size or blur [OK]
Quick Trick: Rotate changes orientation, not size or blur [OK]
Common Mistakes:
  • Confusing rotation with scaling or flipping
  • Assuming it applies image filters like blur
