Vision Transformers for Dense Prediction 论文链接:https://arxiv.org/abs/2103.13413v1论文代码:https://github.com/isl-org/DPT Abstract 本文引入dense vision transformers,它用vision transformers 代替卷积网络作为密集预测(dense prediction)任务的主干。将来自 Vision Transformer 各个阶段的token组装成各种分辨率的...
实验结果 Vision Transformers for Dense Prediction
HRFormer block HRFormer block由两部分组成:local-window self-attention和带有3×3深度卷积的前馈网络。 作者进行了图像分类、姿态估计和语义分割任务的实验,并在各种 Baseline 上取得了竞争性的性能。例如,与DeiT-B相比,HRT-B在ImageNet分类上获得了+1.0%的Top-1精度,参数减少了40%,FLOPs减少了20%。在COCO val...

DPT-Large、DPT-Base和DPT-Hybrid三种模型的不同之处在于ViT中重组连接层的设定，展示了Transformer在深度估计领域的早期尝试。尽管结构相对直观，但实验部分提到的“任意大小图片输入”并非独家创新，当时大部分ViT模型已经具备这种功能。作者通过分享个人经验，表达了对这一观点的反思和对文章期待的落空。实验...
具体而言，研究者基于 FCOS，首次在 dense prediction 上利用全卷积结构做到 E2E，即无 NMS 后处理。研究者首先分析了常见的 dense prediction 方法（如 RetinaNet、FCOS、ATSS 等），并且认为 one-to-many 的 label assignment 是依赖 NMS 的关键。受到 DETR 的启发，研究者设计了一种 prediction-aware one-to-...

We present a High-Resolution Transformer (HRFormer) that learns high-resolution representations for dense prediction tasks, in contrast to the original Vision Transformer that produces low-resolution representations and has high memory and computational cost. We take advantage of the multi-resol...
