所提出的Triplet Attention见下图所示。顾名思义,Triplet Attention由3个平行的Branch组成,其中两个负责捕获通道C和空间H或W之间的跨维交互。最后一个Branch类似于CBAM,用于构建Spatial Attention。最终3个Branch的输出使用平均进行聚合。 1、Cross-Dimension Interaction 传统的计算通道注意力的方法涉及计算一个权值,然后使...
Spatial-Channel Atention(SCA): spatial attention block:采用pyramid scales,序列使用7*7,5*5,3*3卷积。通过逐层上采样实现不同尺度特征的结合获得精确的多尺度信息。并且采用global pooling提供全局context information。使用channel-wise attention map 实现特征的通道选择。上图b显示了channel-wise attention fusion ...

Two feature vectors for each pixel are stacked together as a fusion vector which is refined by an attention module to generate a aggregated feature vector. The attention module includes a channel attention block and a spatial attention block which can effectively leverage the concatenated embeddings ...
Efficient channel and spatial attention block The heart of the ESCN is an efficient channel and spatial attention block. There are two types of attention systems. One is an effective block of channel attention, the other is an effective block of spatial attention. This combination is about placin...
3.论文:CBAM: Convolutional Block Attention Module 链接: 代码: 这是ECCV2018的一篇论文。 这篇文章同时使用了Channel Attention和Spatial Attention,将两者进行了串联(文章也做了并联和两种串联方式的消融实验) Channel Attention方面,大致结构还是和SE相似,不过作者提出AvgPool和MaxPool有不同的表示效果,所以作者对原来...

The spatial attention unit measured the rich context of local features, and the distinction between changed objects and backgrounds was increased using spatial attention in deep features. The channel attention module adjusted the weight of channels and acted as a channel selection process. Mixing two ...
