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.

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

no code implementations9 Feb 2024 Yifeng Bai, Zhirong Chen, Pengpeng Liang, Erkang Cheng

A curve cross-attention module is introduced in the Transformer decoder to calculate similarities between image features and curve queries of lanes.

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.

Traffic Context Aware Data Augmentation for Rare Object Detection in Autonomous Driving

no code implementations1 May 2022 Naifan Li, Fan Song, Ying Zhang, Pengpeng Liang, Erkang Cheng

In this work, we propose a systematic study on simple Copy-Paste data augmentation for rare object detection in autonomous driving.

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.

A Simple and Strong Baseline for Universal Targeted Attacks on Siamese Visual Tracking

no code implementations6 May 2021 Zhenbang Li, Yaya Shi, Jin Gao, Shaoru Wang, Bing Li, Pengpeng Liang, Weiming Hu

In this paper, we show the existence of universal perturbations that can enable the targeted attack, e. g., forcing a tracker to follow the ground-truth trajectory with specified offsets, to be video-agnostic and free from inference in a network.

Planar Object Tracking in the Wild: A Benchmark

no code implementations23 Mar 2017 Pengpeng Liang, Yifan Wu, Hu Lu, Liming Wang, Chunyuan Liao, Haibin Ling

In this paper, we present a carefully designed planar object tracking benchmark containing 210 videos of 30 planar objects sampled in the natural environment.

Adaptive Objectness for Object Tracking

no code implementations5 Jan 2015 Pengpeng Liang, Chunyuan Liao, Xue Mei, Haibin Ling

Noting that the way we integrate objectness in visual tracking is generic and straightforward, we expect even more improvement by using tracker-specific objectness.
