We propose CornerNet, a new approach to object detection where we detect an object bounding box as a pair of keypoints, the top-left corner and the bottom-right corner, using a single convolution neural network. By detecting objects as paired keypoints, we eliminate the need for designing a set of anchor boxes commonly used in prior single-stage detectors. In addition to our novel formulation, we introduce corner pooling, a new type of pooling layer that helps the network better localize corners. Experiments show that CornerNet achieves a 42.2% AP on MS COCO, outperforming all existing one-stage detectors.

  1. Shape-Aware Oriented Bounding Box (OBB) to Horizontal Bounding Box (HBB) Conversion

    cs.CV 2026-08 reject novelty 6.0 of 10

    A shape-aware OBB-to-HBB conversion using a fitted superellipse hull model is proposed, but the derived projection equations are internally inconsistent and the empirical claims are partly overstated.
