G-Rep: Gaussian Representation for Arbitrary-Oriented Object Detection

Understand

Typical representations for arbitrary-oriented object detection tasks include oriented bounding box (OBB), quadrilateral bounding box (QBB), and point set (PointSet).

• Each representation encounters problems that correspond to its characteristics, such as the boundary discontinuity, square-like problem, representation ambiguity, and isolated points, which lead to inaccurate detection.
• Although many effective strategies have been proposed for various representations, there is still no unified solution.
• Current detection methods based on Gaussian modeling have demonstrated the possibility of breaking this dilemma; however, they remain limited to OBB.
