Separable Batch Normalization for Robust Facial Landmark Localization with Cross-protocol Network Training

no code implementations17 Jan 2021 Shuangping Jin, ZhenHua Feng, Wankou Yang, Josef Kittler

Different from the standard BN layer that uses all the training data to calculate a single set of parameters, SepBN considers that the samples of a training dataset may belong to different sub-domains.
