Question 7

+2 marksOne correct option

How does pyramid matching differ from Speeded-Up Robust Features (SURF) in image matching?

  1. A

    Pyramid matching matches images at multiple resolutions using multi- resolution representations, while SURF focuses on detecting and describing local features invariant to scale and rotation.

  2. B

    SURF relies on gradient-based descriptors for feature matching, whereas pyramid matching utilizes histogram-based representations.

  3. C

    Pyramid matching is computationally more efficient compared to SURF, which requires extensive feature extraction and matching procedures.

  4. D

    SURF is more suitable for matching images with complex patterns and cluttered backgrounds, while pyramid matching excels in scenarios where multi-scale matching is critical, such as image registration across different resolutions.

Correct answer

  • A

    Pyramid matching matches images at multiple resolutions using multi- resolution representations, while SURF focuses on detecting and describing local features invariant to scale and rotation.
