三、实验效果 在本文中,除了提出将partial convolution应用到图像修复领域,作者还提出了:图像修复应该是修复不规则的损坏图片的。因此作者还提供了他们的不规则mask数据集Irregular Mask Dataset,并且hole-to-image area ratios有6种不同的大小: (0.01, 0.1], (0.1, 0.2], (0.2, 0.3], (0.3, 0.4], (0.4, 0...

Partial convolution layer是基于pytorch扩展的。 不基于pytorch直接实现的方法是:定义形状为C×H×W的二值掩码binary masks,与相关的图片或者特征相同大小,然后使用一个固定的卷积层来实现掩码的更新操作,固定卷积层的大小和部分卷积层的大小一致,卷积核权重全为1,没有偏置。 Network Design 网络结构类似U-net,用所有...

pytorch代码 论文贡献: 提出了部分卷积(partial convolutions),使得在每一层都使用上一层跟新后的mask,在图片修复上取得了state-of-the-art 的结果。 提出了U-net类型的网络结构,区别在于将传统u-net中的卷积层替换为部分卷积层,解码模块的RELU替换为LeakyRELU。
Note that this is an ongoing re-implementation and I cannot fully reproduce the results. Suggestions and PRs are welcome! This is an unofficial pytorch implementation of a paper,Image Inpainting for Irregular Holes Using Partial Convolutions[Liu+, arXiv2018]. ...
Partial convolution layer is implemented by extending exist- ing standard PyTorch[19], although it can be improved both in time and space using custom layers. The straightforward implementation is to define binary masks of size C×H×W, the same size with their associated images/features, and ...
