上图是一个使用在ResNet-50上的例子,可以看出来和原始的ResNet的区别就是在每个阶段的Residual Block之间增加了Attention Module,可以看到最小的输出特征图的宽高大小为7x7,上文中说到,在每一个Soft Mask Branch中对于input的特征图,会不断地卷积操作之后使用Max-Pooling降采样,文中降采样的宽高维度下限就是网络...
概括一下,在 SENet、BAM、CBAM 中的 Channel Attention 是只有 Channel 维度不一样,Spatial 维度所有点的权重都一样;而本文的 Channel Attention 是只在计算权重也就是归一化的时候考虑了 Channel 维度上的点,而没有考虑 Spatial 权重上的点,因此不同Spatial 上点的权重还是不同的,因为他们各自 Channel 维度上的...
