截止2019-11-05 该论文是preprint
Segmentation-Aware Image Denoising without Knowing True Segmentation
相当与分割网络可以训练的参数只有最后转成K channels 的那些3*3卷积层 和上采样层,而且没有用到语义信息标签, 而且特征嵌入网络的参数是固定的,用的是IMAGENET的欲训练,,但是居然可以work!!!
Segmentation-Aware Image Denoising without Knowing True Segmentation
论文阅读记录 2019 prprint
这篇论文利用语义网络信息来辅助去噪,但是语意网路那边不借助标签监督信息,这区别与传统的联合训练方法)
On the other hand, in the metric of PSNR,
a model trained by minimizing MSE on the image domain
should always outperform a model trained by minimizing a
hybrid weighted loss. Therefore, we emphasize that the goal of
our following experiments is not to pursue the highest PSNR,
but to quantitatively demonstrate the different behaviors between
models with and without segmentation awareness.
论文中这段话说明了 采用了joint training 后 psnr大部分时候比不过直接使用MSE训练的去噪模型
从实验表格看确实如此,说明了high-level和low-level task之间的gap. 但是差距似乎不大在论文所提供的实验中. (CDN-CNN-B是直接训练的去噪模型, 其余两个是采用了两种不同方式的联合训练的模型:
