将anchor-free的检测头换成anchor-based,其他不变,验证anchor-free的有效性。结论anchor-free能显著增强特征鉴别性。 采用不同的下采样步长,发现相同步长下,anchor-free优于anchor-based方法/ 分辨率较高的情形,anchor-based反而性能下降了,作者认为是未对齐的anchors更多导致训练不充分。 对比了不同backbone 不同的bac...
从其他领域借鉴了一些方法和概念处理这些存在的问题,提供了一个简单却强大的baseline。 方法介绍 本文方法的框架图: image.png backbone 基干网络采用的是ResNet-34,然后不同的stage之间采用修改版的Deep Layer Aggregation (DLA)进行融合,最终输出的特征map相对于输入下采用的4倍,而不是原来的32倍,能有效提升检测的...
Tracking by detection has been the prevailing paradigm in the field of Multi-object Tracking (MOT). These methods typically rely on the Kalman Filter to estimate the future locations of objects, assuming linear object motion. However, they fall short when tracking objects exhibiting nonlinear and ...

3D multi-object tracking (MOT) is essential to applications such as autonomous driving. Recent work focuses on developing accurate systems giving less attention to computational cost and system complexity. In contrast, this work proposes a simple real-time 3D MOT system with strong performance. Our...
3D multi-object tracking (MOT) is an essential component for many applications such as autonomous driving and assistive robotics. Recent work on 3D MOT focuses on developing accurate systems giving less attention to practical considerations such as computational cost and system complexity. In contrast,...
