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...

输入尺寸设为(B,3,512,512)。为深入理解，还查阅了《图像分割UNet系列---Attention Unet详解》，对相关实现有了更全面的了解。通过GitHub - LeeJunHyun/Image_Segmentation: Pytorch实现的U-Net, R2U-Net, Attention U-Net, and Attention R2U-Net项目，获取了更多实践案例与代码细节。

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...
