摘要:

在现实交通场景中,不同尺度的目标通常分布于杂乱背景中,这对准确检测构成巨大挑战。尽管当前基于Mamba的方法能有效建模长距离依赖,但仍难以捕捉具有丰富局部细节的小目标,阻碍了局部结构与全局语义的联合建模。此外,状态空间模型由于扁平序列建模和不足的空间归纳偏差,表现出有限的层次特征表示和弱跨尺度交互,导致在复杂场景中性能欠佳。为解决这些问题,本文提出Mamba与可变形扩张卷积网络(MDDCNet)用于准确的交通目标检测。在MDDCNet中,精心设计的混合主干网络包含连续的多尺度可变形扩张卷积(MSDDC)块和Mamba块,能够从局部细节到全局语义实现层次化特征表示。同时,设计了通道增强前馈网络(CE-FFN)以克服传统前馈网络的有限通道交互能力,同时构建了基于Mamba的注意力聚合特征金字塔网络(A^2FPN)以实现增强的多尺度特征融合与交互。在公共基准和真实世界数据集上的大量实验结果表明,本文方法在各种先进检测器中表现更优。代码可在https://github.com/Bettermea/MDDCNet获取。

英文摘要:

In a real-world traffic scenario, varying-scale objects are usually distributed in a cluttered background, which poses great challenges to accurate detection. Although current Mamba-based methods can efficiently model long-range dependencies, they still struggle to capture small objects with abundant local details, which hinders joint modeling of local structures and global semantics. Moreover, state-space models exhibit limited hierarchical feature representation and weak cross-scale interaction due to flat sequential modeling and insufficient spatial inductive biases, leading to sub-optimal performance in complex scenes. To address these issues, we propose a Mamba with Deformable Dilated Convolutions Network (MDDCNet) for accurate traffic object detection in this study. In MDDCNet, a well-designed hybrid backbone with successive Multi-Scale Deformable Dilated Convolution (MSDDC) blocks and Mamba blocks enables hierarchical feature representation from local details to global semantics. Meanwhile, a Channel-Enhanced Feed-Forward Network (CE-FFN) is further devised to overcome the limited channel interaction capability of conventional feed-forward networks, whilst a Mamba-based Attention-Aggregating Feature Pyramid Network (A^2FPN) is constructed to achieve enhanced multi-scale feature fusion and interaction. Extensive experimental results on public benchmark and real-world datasets demonstrate the superiority of our method over various advanced detectors.
