利用这一发现,他们在交替方向乘子法(ADMM)优化框架下使用即插即用(Plug-and-Play)技巧,将图像数据预训练的去噪器(Denoiser)插入三维声速场的重建过程中以提供数据驱动的先验知识,同时结合模型驱动的低秩张量建模,实现了精细化的声速场重...
基于这种形式上的相似性, 我们考虑用现有的去噪算法替代 ADMM 中对v-子问题的优化. 将去噪算法抽象为f(\cdot,\eta), 保留\eta是因为去噪算法中常常需要指定噪声的大小. 于是 PnP-ADMM 写作 \left\{ \begin{aligned} x^{k+1}&=(A^\top A+\frac{\sigma^2}{\eta}I)^{-1}\left(A^\top y+\frac...
plug-and-play 2D ADMM-Net (PAN)We propose a deep learning architecture, dubbed Plug-and-play 2D ADMM-Net (PAN), by combining model-driven deep networks and data-driven deep networks for effective high-resolution 2D inverse synthetic aperture radar (ISAR) imaging with various ...
Alternating direction method of multiplier (ADMM) is a widely used algorithm for solving constrained optimization problems in image restoration. Among many useful features, one critical feature of the ADMM algorithm is its modular structure, which allows one to plug in any off-the-shelf image denois...

方法: 应用ADMM技术,分离变量以实现将MAP估计问题解耦为先验和前模型问题,一个是前向模型一个是先验问题。一个模块对应着降噪算法只依靠于先验,第二个模块对应着应用l2正则化的反演问题只依靠于前向模型。 MAP计算函数去解决反演问题 带求量^xx^的MAP估计: ^x=x^=argmin-logp(y|x)p(y|x)-logp(x)p(x)...
Specifically, a parameterized plug-and-play alternating direction method of multipliers (3pADMM) is proposed for the general penalized weighted least-squares (PWLS) model, and then, by adopting the basic idea of DL, the parameterized plug-and-play (3p) prior and the related parameters are ...
Sections 2.1 and 2.2 review the alternating direction method of multipliers (ADMM) and the plug-and-play framework. After presenting the necessary building blocks, Sect. 3 introduces our approach to class-adapted BID for images with one or more specific classes. The experimental evaluation of our...
