• Abstract: Anchor free methods have defined the new frontier in state-of-the-art object detection researches where accurate bounding box estimation is the key to the success of these methods. However, even the bounding box has the highest confidence score, it is still far from perfect at localization. To this end, we propose a box reorganization method(DDBNet), which can dive deeper into the box for more accurate localization. At the first step, drifted boxes are filtered out because the contents in these boxes are inconsistent with target semantics. Next, the selected boxes are broken into boundaries, and the well-aligned boundaries are searched and grouped into a sort of optimal boxes toward tightening instances more precisely. Experimental results show that our method is effective which leads to state-of-the-art performance for object detection.

• Rigidity-Aware Detection for 6D Object Pose Estimation [60.88857851869196]
  Most recent 6D object pose estimation methods first use object detection to obtain 2D bounding boxes before actually regressing the pose. We propose a rigidity-aware detection method exploiting the fact that, in 6D pose estimation, the target objects are rigid. Key to the success of our approach is a visibility map, which we propose to build using a minimum barrier distance between every pixel in the bounding box and the box boundary.

  Oriented object detection emerges in many applications from aerial images to autonomous driving.

• Boundary Distribution Estimation for Precise Object Detection [12.247010914825971]
  In the field of object detection, the task of object localization is typically accomplished through a dedicated that emphasizes bounding box regression. This traditionally predicts the object's position by regressing the box's center position and scaling factors. In this paper, we address the shortcomings of previous methods through theoretical analysis and experimental verification. Our approach enhances the accuracy of bounding box localization by refining the box edges based on the estimated distribution at the object's boundary.
