Spatial transformer networks boils down to three main components : The localization network is a regular CNN which regresses the transformation parameters. The transformation is never learned explicitly from this dataset, instead the network learns automatically the spatial transformations that enhances the ...
(STCNN Single): a spatial transformer immediately following the input (ST-CNN Multi): where the localization networks are all two layer fully connected networks with 32 units per layer CNN-baseline conv[48,5,1,2]-max[2]- conv[64,5,1,2]-conv[128,5,1,2]-max[2]- ...

这个spatial transformer可以放在一个CNN网络里的任何地方,从而得到一个spatial transform network。 优点:据说运行的很快,不会影响速度,还可以提高效率,对特征图进行向下或者向上采样。 4. 代码实现[4] 这里用了pytorch的VGG模型,加上spatial transformer,做一个FashionMNIST的分类。
