摘要:

单图像超分辨率(Single Image Super-resolution,SISR)是一种从低分辨率(Low Resolution,LR)图像获得高分辨率(High Resolution,HR)图像的图像处理任务。最近,由于特征提取的能力,一系列深度学习方法为SISR带来了重要的关键改进。然而,我们观察到,无论多深的网络设计,他们通常不具有良好的泛化能力,这导致了事实上,几乎所有现有的SR方法有弱纹理细节的恢复性能差。为了解决这些问题,我们提出了一种弱纹理信息映射引导的深度残差网络图像超分辨率。该算法由三个子网络组成,一个主网络提取主特征并融合弱纹理细节,另外两个辅助网络提取落在主网络中的弱纹理细节。两部分网络协同工作,辅助网络预测并将微弱的纹理信息整合到主网络中,有利于主网络学习更多不显眼的细节。实验结果表明,我们的方法的性能达到最先进的定量。具体来说,我们的方法的图像超分辨率结果具有更多的弱纹理细节。

英文摘要:

Single image super-resolution (SISR) is an image processing task which obtains high-resolution (HR) image from a low-resolution (LR) image. Recently, due to the capability in feature extraction, a series of deep learning methods have brought important crucial improvement for SISR. However, we observe that no matter how deeper the networks are designed, they usually do not have good generalization ability, which leads to the fact that almost all of existing SR methods have poor performances on restoration of the weak texture details. To solve these problems, we propose a weak texture information map guided image super-resolution with deep residual networks. It contains three sub-networks, one main network which extracts the main features and fuses weak texture details, another two auxiliary networks extract the weak texture details fallen in the main network. Two part of networks work cooperatively, the auxiliary networks predict and integrates week texture information into the main network, which is conducive to the main network learning more inconspicuous details. Experiments results demonstrate that our method's performs achieve the state-of-the-art quantitatively. Specifically, the image super-resolution results of our method own more weak texture details.
