以ViT为backbone的dense vision transformers,主要由三个部分组成:transformer encoder、convolutional decoder、fusion 与ViT中使用的bag-of-words表示类似,DPT首先将图像划分成大小为 p^2 的patch,其次通过Embed(线性映射或ResNet)转换至特征空间,每一个“word”视为一个token,token与patch一一对应(未改变分辨率),经过...

另外,Transformer受益于形状偏置(Are convolutional neural networks or transformers more like human vision?)。相反,CNN可以利用来自平移不变性的局部连通性,图像中每个Patch在处理时都具有相同的比重。这种归纳偏置鼓励CNN在对视觉对象进行分类时,相比形状,对纹理有更强的依赖性。于是MPViT中就以一种相互补充的形式...
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...
