ASpatial Attention Moduleis a module for spatial attention in convolutional neural networks. It generates a spatial attention map by utilizing the inter-spatial relationship of features. Different from the channel attention, the spatial attention focuses on where is an informative part, which is comple...
(2)使用Spatial-Channel Attention module 提取multi-scale和global context features 来encode local 和global information。SCA具有空间和通道注意性,能够保证空间和通道特征的recalibrating。因此可以有效的区分特征并抑制不明显的特征。 (3)decoder:Extension Spatial Upsample module:结合低分辨率特征图和多尺度低层次特征协...
对通道生成掩码mask,进行打分,代表是senet,Channel Attention Module。 混合域——空间域的注意力是忽略了通道域中的信息,将每个通道中的图片特征同等处理,这种做法会将空间域变换方法局限在原始图片特征提取阶段,应用在神经网络层其他层的可解释性不强。 卷积神经网络中常用的Attention 在卷积神经网络中常用到的主要有...
We propose a Grad-CAM guided channel-spatial attention module for the FGVC, which employs the Grad-CAM to supervise and constrain the attention weights by generating the coarse localization maps. To demonstrate the effectiveness of the proposed method, we conduct comprehensive experiments on three ...
In this paper, we propose SCAM-YOLOv5, which uses a modified attention mechanism and Ghost convolution to improve the YOLOv5s network, achieving gratifying results. Compared with the vanilla network, the mAP is increased by 2.6% on the VOC dataset, while the model file is only increased by ...
spatial attention and channel attention 这里作者想，针对mask branch,同样可以采用一些方法进行约束，使之...
【嵌牛导读】本文中研究了轻量且有效的注意力机制,并提出了Triplet Attention。 【嵌牛鼻子】Triplet Attention 【嵌牛提问】这种注意力机制是怎样的? 【嵌牛正文】 1、简介和相关方法 最近许多工作提出使用Channel Attention或Spatial Attention,或两者结合起来提高神经网络的性能。这些Attention机制通过建立Channel之间的依赖...
In this paper, to accomplish this goal, it proposes to combine the channel attention and spatial attention module (C-SAM), the C-SAM can mine deeply more effective information using samples of different classes that exist in different tasks. The residual network is used to alleviate the loss ...

在上一篇讲SENet的文章中,里面提到的Squeeze-excitation block引入的技术可以被称作是通道注意力机制:channel attention。 既然提到了注意力机制,那么这几篇就来说说注意力机制的事情,SENet是在2019年提出的,在2015年的时候,就有一篇论文提出了另一个维度的注意力机制:空间注意力机制,论文为:Spatial Transformer Networks...
