Publication number: 20220375237Abstract: An end-to-end trainable grouped mathematically differentiable non-maximal suppression (NMS) technique is presented for monocular 3D object detection. First, formulate NMS as a matrix operation and then group and mask the boxes in an unsupervised manner to obtain a simple closed-form expression of the NMS. This technique addresses the mismatch between training and inference pipelines and, therefore, forces the network to select the best 3D box in a differentiable manner. As a result, the proposed technique achieves state-of-the-art monocular 3D object detection results on the KITTI benchmark dataset performing comparably to monocular video-based methods.Type: ApplicationFiled: February 22, 2022Publication date: November 24, 2022Applicant: Board of Trustees of Michigan State UniversityInventors: Xiaoming LIU, Abhinav KUMAR, Garrick BRAZIL
