Multi-scale Transformer 希望定位篡改伪影与其他区域不一致,因此需要建模长期关系,计算相似度。 引入多尺度的transformer,覆盖不同大小的区域 输入图片(HW3)再backbone提取shallow feature,然后分成不同的尺寸(不同的头)计算patch-wise的self attention,即每个patch(rh*rh*c)展成一维向量,使用fc层embed到query embedding...
Position-wise Attention Block and Multi-scale Fusion Attention Block. We adopt the improved encoder-decoder architecture of U-Net for liver and tumors segmentation in the paper. The Res-block consists of three 3×3 Convolution blocks and residual connections to extract high-dimensional feature inform...
考虑到多分支的高度复杂性HR架构和Self-Attention操作,简单地用Transformer Block替换HRNet中的所有残差快,将遇到严重的可伸缩性问题。如果没有仔细的Architecture-block协同优化,继承的强大的可表示性将被高昂的硬件成本所淹没。 为了增强ViT的可表征性,以生成语义丰富和位置精确的特征,在本工作中提出HRViT,一种专为高...

虽然CoaT通过co-scale机制,运行跨层Attention,从而表征了粗粒度和细粒度,但是这种机制需要过多的计算和存储负担,因为他需要在基础模型上,额外添加一个跨层注意结构。因此对于ViT变体而言,多尺度特征表征仍然存在提升的空间。 具体做法 这篇文章就专注于如何为密集预测任务用ViT有效表示多尺度特征。
In this study, we propose the multi-attention residual network (MARN) to address these problems. Specifically, we propose a new multi-attention residual block (MARB), which is composed of attention mechanism and multi-scale residual network. At the beginning of each residual block, the channel...
