✨✨✨魔改创新RT-DETR

🚀🚀🚀引入前沿顶会创新，助力RT-DETR

🍉🍉🍉基于ultralytics优化，与YOLO完美结合

1.RT-DETR介绍

论文： https://arxiv.org/pdf/2304.08069.pdf

RT-DETR (Real-Time DEtection TRansformer) ，一种基于 DETR 架构的实时端到端检测器，其在速度和精度上取得了 SOTA 性能

为什么会出现：

YOLO 检测器有个较大的待改进点是需要 NMS 后处理，其通常难以优化且不够鲁棒，因此检测器的速度存在延迟。为避免该问题，我们将目光移向了不需要 NMS 后处理的 DETR，一种基于 Transformer 的端到端目标检测器。然而，相比于 YOLO 系列检测器，DETR 系列检测器的速度要慢的多，这使得"无需 NMS "并未在速度上体现出优势。上述问题促使我们针对实时的端到端检测器进行探索，旨在基于 DETR 的优秀架构设计一个全新的实时检测器，从根源上解决 NMS 对实时检测器带来的速度延迟问题。

RT-DETR是第一个实时端到端目标检测器。具体而言，我们设计了一个高效的混合编码器，通过解耦尺度内交互和跨尺度融合来高效处理多尺度特征，并提出了IoU感知的查询选择机制，以优化解码器查询的初始化。此外，RT-DETR支持通过使用不同的解码器层来灵活调整推理速度，而不需要重新训练，这有助于实时目标检测器的实际应用。RT-DETR-L在COCO val2017上实现了53.0%的AP，在T4 GPU上实现了114FPS，RT-DETR-X实现了54.8%的AP和74FPS，在速度和精度方面都优于相同规模的所有YOLO检测器。RT-DETR-R50实现了53.1%的AP和108FPS，RT-DETR-R101实现了54.3%的AP和74FPS，在精度上超过了全部使用相同骨干网络的DETR检测器。

2.EMA介绍

论文：https://arxiv.org/abs/2305.13563v1

录用：ICASSP2023

通过通道降维来建模跨通道关系可能会给提取深度视觉表示带来副作用。本文提出了一种新的高效的多尺度注意力(EMA)模块。以保留每个通道上的信息和降低计算开销为目标，将部分通道重塑为批量维度，并将通道维度分组为多个子特征，使空间语义特征在每个特征组中均匀分布。

本文提出了一种新的跨空间学习方法，并设计了一个多尺度并行子网络来建立短和长依赖关系。
1)我们考虑一种通用方法，将部分通道维度重塑为批量维度，以避免通过通用卷积进行某种形式的降维。
2)除了在不进行通道降维的情况下在每个并行子网络中构建局部的跨通道交互外，我们还通过跨空间学习方法融合两个并行子网络的输出特征图。
3)与CBAM、NAM[16]、SA、ECA和CA相比，EMA不仅取得了更好的结果，而且在所需参数方面效率更高。
