Enhancing 3D Object Detection with 2D Detection-Guided Query Anchors

no code implementations10 Mar 2024 Haoxuanye Ji, Pengpeng Liang, Erkang Cheng

A 2D bounding box of an object in an image is lifted to a set of 3D anchors by associating each sampled point within the box with depth, yaw angle, and size candidates.

Multi-Correlation Siamese Transformer Network with Dense Connection for 3D Single Object Tracking

1 code implementation18 Dec 2023 Shihao Feng, Pengpeng Liang, Jin Gao, Erkang Cheng

Instead of performing correlation of the two branches at just one point in the network, in this paper, we present a multi-correlation Siamese Transformer network that has multiple stages and carries out feature correlation at the end of each stage based on sparse pillars.

CircleFormer: Circular Nuclei Detection in Whole Slide Images with Circle Queries and Attention

1 code implementation30 Aug 2023 Hengxu Zhang, Pengpeng Liang, Zhiyong Sun, Bo Song, Erkang Cheng

Inspired by the recent anchor free CNN-based circular object detection method (CircleNet) for ball-shape glomeruli detection in renal pathology, in this paper, we present CircleFormer, a Transformer-based circular medical object detection with dynamic anchor circles.

CurveFormer: 3D Lane Detection by Curve Propagation with Curve Queries and Attention

no code implementations16 Sep 2022 Yifeng Bai, Zhirong Chen, Zhangjie Fu, Lang Peng, Pengpeng Liang, Erkang Cheng

In this paper, we propose CurveFormer, a single-stage Transformer-based method that directly calculates 3D lane parameters and can circumvent the difficult view transformation step.

Coarse-to-fine Semantic Localization with HD Map for Autonomous Driving in Structural Scenes

no code implementations6 Jul 2021 Chengcheng Guo, Minjie Lin, Heyang Guo, Pengpeng Liang, Erkang Cheng

To this end, we formulate vision-based localization as a data association problem that maps visual semantics to landmarks in HD map.

Curvilinear Structure Tracking by Low Rank Tensor Approximation with Model Propagation

no code implementations CVPR 2014 Erkang Cheng, Yu Pang, Ying Zhu, Jingyi Yu, Haibin Ling

Robust tracking of deformable object like catheter or vascular structures in X-ray images is an important technique used in image guided medical interventions for effective motion compensation and dynamic multi-modality image fusion.
