代码地址:https://github.com/ozan-oktay/Attention-Gated-Networks Attention UNet在UNet中引入注意力机制,在对编码器每个分辨率上的特征与解码器中对应特征进行拼接之前,使用了一个注意力模块,重新调整了编码器的输出特征。该模块生成一个门控信号,用来控制不同空间位置处特征的重要性,如下图中红色圆圈所示。 Attenti...

We proposed a sequence of preprocessing techniques followed by deeply supervised UNet to improve the accuracy of segmentation of the brain vessels leading to a stroke. To combine the low and high semantics, we applied the attention mechanism. This mechanism focuses on relevant associations and ...
The attention gates in the generator focuses on the activation of relevant information instead of allowing all information to pass through the skip connections in the Res-UNet. Our model performed well in comparison to the baseline models i.e. UNet, Res-UNet, and Res-UNet with attention gates...
