Summary
This study introduces an efficient pyramid relinking segmentation scheme, proving some images are unsegmentable in principle. The new method offers sublinear time complexity for robust image segmentation and region matching.
Area of Science:
- Computer Vision

Background:
- Pyramid architectures are common in image segmentation.
- Existing segmentation schemes have limitations in efficiency and robustness.
- The theoretical limits of image segmentation using pyramid methods require clarification.
Purpose of the Study:
- To establish a theoretical foundation for pyramid-based image segmentation.
- To develop an efficient and robust segmentation scheme using pyramid relinking.
- To demonstrate the effectiveness of the proposed method in region matching tasks.
Main Methods:
