Dynamic Scene Deblurring with Parameter Selective Sharing andNested Skip Connections
Abstract
Dynamic Scene deblurring is a challenging low-level vision task where spatially variant blur is caused by many
factors, e.g., camera shake and object motion. Recent study has made significant progress. Compared with the
parameter independence scheme [19] and parameter sharing scheme [33], we develop the general principle for constraining the deblurring network structure by proposing the
generic and effective selective sharing scheme. Inside the
subnetwork of each scale, we propose a nested skip connection structure for the nonlinear transformation modules to
replace stacked convolution layers or residual blocks. Besides, we build a new large dataset of blurred/sharp image
pairs towards better restoration quality. Comprehensive experimental results show that our parameter selective sharing scheme, nested skip connection structure, and the new
dataset are all significant to set a new state-of-the-art in
dynamic scene deblurring.
