The paper from The Hong Kong University of Science and Technology introduces 360VOTS, the first comprehensive benchmark dataset and a general framework for visual object tracking and segmentation in omnidirectional videos. It addresses unique challenges like spherical distortion and border crossing with a novel representation and tailored metrics, enabling existing perspective-based models to achieve substantial performance gains (e.g., AiATrack-360 improved by 12.9% in dual success).
Key insights
- Traditional 2D bounding boxes and metrics are insufficient for accurately representing and evaluating object localization and segmentation in highly distorted 360° equirectangular projections.
- Existing state-of-the-art perspective vision models can be effectively leveraged for omnidirectional tasks by integrating them with a framework that handles the unique geometric and topological properties of 360° video.
- A dedicated, densely annotated large-scale benchmark dataset with specific 360° challenges is crucial for training robust models and standardizing evaluation in this emerging field.
