HeightFormer: Explicit Height Modeling without Extra Data for Camera-only 3D Object Detection in Bird's Eye View

no code implementations25 Jul 2023 Yiming Wu, Ruixiang Li, Zequn Qin, Xinhai Zhao, Xi Li

In this work, we propose to explicitly model heights in the BEV space, which needs no extra data like LiDAR and can fit arbitrary camera rigs and types compared to modeling depths.

GaitMPL: Gait Recognition with Memory-Augmented Progressive Learning

no code implementations6 Jun 2023 Huanzhang Dou, Pengyi Zhang, Yuhan Zhao, Lin Dong, Zequn Qin, Xi Li

In this work, we propose to solve the hard sample issue with a Memory-augmented Progressive Learning network (GaitMPL), including Dynamic Reweighting Progressive Learning module (DRPL) and Global Structure-Aligned Memory bank (GSAM).

Ultra Fast Deep Lane Detection with Hybrid Anchor Driven Ordinal Classification

2 code implementations15 Jun 2022 Zequn Qin, Pengyi Zhang, Xi Li

With the help of the anchor-driven representation, we then reformulate the lane detection task as an ordinal classification problem to get the coordinates of lanes.

MonoGround: Detecting Monocular 3D Objects from the Ground

1 code implementation CVPR 2022 Zequn Qin, Xi Li

To alleviate this problem, we propose to introduce the ground plane as a prior in the monocular 3d object detection.

VersatileGait: A Large-Scale Synthetic Gait Dataset with Fine-GrainedAttributes and Complicated Scenarios

no code implementations5 Jan 2021 Huanzhang Dou, Wenhu Zhang, Pengyi Zhang, Yuhan Zhao, Songyuan Li, Zequn Qin, Fei Wu, Lin Dong, Xi Li

With the motivation of practical gait recognition applications, we propose to automatically create a large-scale synthetic gait dataset (called VersatileGait) by a game engine, which consists of around one million silhouette sequences of 11, 000 subjects with fine-grained attributes in various complicated scenarios.

FcaNet: Frequency Channel Attention Networks

7 code implementations ICCV 2021 Zequn Qin, Pengyi Zhang, Fei Wu, Xi Li

With the proof, we naturally generalize the compression of the channel attention mechanism in the frequency domain and propose our method with multi-spectral channel attention, termed as FcaNet.

CoDiNet: Path Distribution Modeling with Consistency and Diversity for Dynamic Routing

1 code implementation29 May 2020 Huanyu Wang, Zequn Qin, Songyuan Li, Xi Li

In this paper, we see dynamic routing networks in a fresh light, formulating a routing method as a mapping from a sample space to a routing space.

Ultra Fast Structure-aware Deep Lane Detection

8 code implementations ECCV 2020 Zequn Qin, Huanyu Wang, Xi Li

Modern methods mainly regard lane detection as a problem of pixel-wise segmentation, which is struggling to address the problem of challenging scenarios and speed.
