GA-DAN: Geometry-Aware Domain Adaptation Network for Scene Text Detection and Recognition
The contributions
- 在geometry 和 appearance 两个维度上进行建模,消除domain shifts
- 设计了一种新颖的多模态sptial learning mechanism同时引入了一种spatial transformation discriminator 去实现multi-modal adaptation in geometry space
- 设计了一个disentangled cycle-consistency loss 可以平衡appearance和geometry 的一致性。
