easy📝 Conceptual Q11 of 15
SciPy - Image Processing (scipy.ndimage)
What is the main purpose of connected component labeling in image processing?
ATo enhance image contrast
BTo convert color images to grayscale
CTo identify and label groups of connected pixels in binary images
DTo compress image file size
Step-by-Step Solution
Solution:
  1. Step 1: Understand connected component labeling

    It finds groups of connected pixels in binary images and assigns unique labels to each group.
  2. Step 2: Compare with other image tasks

    Other options like grayscale conversion, contrast enhancement, and compression do not involve labeling connected pixels.
  3. Final Answer:

    To identify and label groups of connected pixels in binary images -> Option C
  4. Quick Check:

    Connected component labeling = identify connected pixel groups [OK]
Quick Trick: Remember: labeling means assigning unique IDs to connected pixels [OK]
Common Mistakes:
  • Confusing labeling with color conversion
  • Thinking it compresses images
  • Mixing it up with image enhancement
