Salvage of Supervision in Weakly Supervised Object Detection and Segmentation
Summary
This study introduces Salvage of Supervision (SoS), a novel framework to improve weakly supervised vision tasks. SoS effectively uses all available signals, significantly closing the accuracy gap with fully supervised methods.
Area of Science:
- Computer Vision
- Machine Learning
Background:
- Weakly supervised vision tasks (detection, segmentation) face accuracy gaps due to limited annotations.
- Existing methods often rely on specific pretraining or backbone limitations.
Purpose of the Study:
- To propose a new framework, Salvage of Supervision (SoS), to enhance weakly supervised vision tasks.
- To effectively utilize all available supervisory signals, including weak image-level labels and pseudo-labels.
Main Methods:
- Developed SoS-WSOD for weakly supervised object detection, integrating semi-supervised learning.
- Designed SoS to be adaptable for semantic and instance segmentation tasks.
- Removed traditional constraints like ImageNet pretraining and restricted backbone usage.
Main Results:
- SoS-WSOD significantly reduces the accuracy gap between weakly and fully supervised object detection.
- The SoS framework demonstrates improved performance and generalization across various weakly supervised vision benchmarks.
- Achieved substantial performance boosts in weakly supervised detection and segmentation tasks.
Conclusions:
- The Salvage of Supervision framework offers a powerful approach to harness underutilized supervisory signals.
- SoS enhances the efficacy of weakly supervised learning in computer vision, enabling broader applicability.
- This method overcomes limitations of prior weakly supervised techniques, paving the way for more robust models.
