如上图,用GAN学习自然图像的先验、用其分布作为自然图像的近似表征,用GAN给出的 “近似自然图像”作为复原结果来恢复失真图。模型主打Deep Generative Prior简称DGP,是在对标DIP(Deep Image Prior)。 复原过程 Motivation跟GAN Inversion有啥关系呢?关联就在于“失真图像的复原过程”。 之前提到我们用GAN模型近似表征自...
我们的Deep Generative Prior [1]很荣幸被接收为ECCV2020的oral presentation。本文提出一种挖掘预训练的对抗生成网络(GAN)中图像先验的方式。无需针对特定任务设计,我们实现了多种图像复原(上色,补全,超分…

In this work, we focus on a learning-based prior knowledge generator, and address the important caveats that arise in the context. Unlike hand-designed priors, we use existing subsurface velocity models to train a deep generative adversarial network (GAN) that generates artificial models from a ...
Deep Image Prior 步骤 ẋ = corrupted image(observed) 1.初始化z。 :用均匀噪声或任何其他随机图像填充输入z。 2.使用基于梯度的方法求解和优化函数。 3.最后,当我们找到最佳θ时,我们可以通过将固定输入z向前传递到具有参数θ的网络来获得最佳图像。
We go on further to show that including a generative prior is, in general, a good idea in image deblurring on even richer images e.g. arbitrary natural images, by demonstrating that untrained convolutional generative networks can act as good image priors based on their structure alone. Our ...

inverse approaches using deep generative priors. Such an approach will not require re-training a separate inverse model for each forward model variation; hence, one can run many numerical experiments to investigate the model mismatch problem. This will also help investigate other behaviors, such as ...
Deep Matching Prior Network 金连文教授发表在 CVPR2017 上的工作提出了一个重要观点:在生成 proposal 时回归矩形框不如回归一个任意多边形。 理由:这是因为文本在图像中更多的是具有不规则多边形的轮廓。他们在SSD(Single ShotMultiBox Detector)的检测框架基础上,将回归边界框的过程和匹配的过程都加入到网络结构中,...
