StainNet: a fast and robust stain normalization network [article]

Hongtao Kang, Die Luo, Weihua Feng, Junbo Hu, Shaoqun Zeng, Tingwei Quan, Xiuli Liu
2021 arXiv   pre-print
Here, we use distillation learning to reduce the complexity of deep learning methods and a fast and robust network called StainNet to learn the color mapping between the source image and target image.  ...  The pixel-to-pixel manner restricts the network size and avoids artifacts in the style transformation.  ...  Our proposed StainNet can achieve good results because of its robustness and less relying on the distribution of training set.  ...
