dual channel and spatial attention moduleMRI imagespine segmentationAccurate image segmentation plays an essential role in diagnosing and treating various spinal diseases. However, traditional segmentation methods often consume a lot of time and energy. This research proposes an innovative deep‐learning‐...
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,所以作者对原来的特征在Spatial维度分别进行了AvgPool和MaxPool,然后用SE的结构提取channel attention,注意这里是参数共享的,然后将两个特征相加后做归一化,就得到了注意力矩阵。 Spatial Attention和Channel Attention类似,先在cha...

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, 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 ...
The attention mechanism is a good solution to this problem18,19. Zhao et al.20 embedded an improved channel and spatial attention module in residual structure and focused attention on effective information of feature maps. Li et al.21 combined Dual-stage Attention-based Recurrent Neural Network (...

The features of each location are aggregated through the spatial attention module, so that similar features promote each other in space size. At the same time, the channel attention module treats each channel of the feature map as a feature detector and emphasizes the channel dependency between ...
