2. Interpreting Instance Normalization: 略 3. Adaptive Instance Normalization: 既然IN 可以根据 affine parameters 将输入归一化为 single style,那么,有没有可能,我们给定多种自适应的 affine transformations 来生成任意给定类型的图像呢?基于该动机,作者对 IN 的技术进行了拓展,提出了 Adaptive Instance Normalizatio...

This is an unofficial pytorch implementation of a paper, Arbitrary Style Transfer in Real-time with Adaptive Instance Normalization [Huang+, ICCV2017]. I'm really grateful to theoriginal implementationin Torch by the authors, which is very useful. ...
Eq. (8) represents the distribution of the feature uncertainties (represented by the vector b) in the UDnet’s probabilistic adaptive instance normalization (PAdaIN) block. The distribution is also assumed to be normal, but with a different subscript s to distinguish it from the distribution in...
Fig. 1. Illustration of the proposed SAN-Net for brain stroke lesion segmentation: (a) Masked Adaptive Instance Normalization (MAIN) standardizes the MR images into a site-unrelated style; (b) Site classifier with gradient reversal layer (−Δ) performs site-invariant learning; (c) Symmetry-...
Instead of huge instance-adaptive models, we resort to a parameter-efficient fine-tuning method, i.e., scale and shift deep features (SSF), upon a pre-trained model. Specifically, we first train an SSF pool for each client, and aggregate these SSF pools on the server s...
Our MAEG-Net was implemented using the PyTorch deep learning framework, with all experiments conducted on two NVIDIA RTX 2080Ti GPUs. The network was trained with a batch size of 16, and the learning rate was set to 1e-4. The training was performed over 200 epochs, with an early stoppin...
方法的核心是加入了一个adaptive instance normalization (AdaIN) layer, 这个层做的事情就是利用待转换风格图片的特征的均值和方差,用来改变原来图片的均值和方差 打个比方有x,y两张图片,想把y上的风格转移到x上去,首先吧x,y的encode后的特征提取出来求均值和方差,x做归一化,再用y的均值方差进行分布调整 ...
