A Global-Local Blur Disentangling Network for Dynamic Scene Deblurring
2021
Applied Sciences
Preserved Fulltext
The visualized feature maps of different branches indicated that our dual-branch network can decouple the global and local blur features efficiently. ...
Experimental results show that the proposed dual-branch blur disentangling network can improve both the subjective and objective deblurring effects for real captured images. ...

Our work represents the first attempt to simulate a camera sensor's behavior leveraging both the advantage of traditional raw sensor features and the power of data-driven deep learning. ...
Other methods [9, 12] first learn to segment the foreground objects segmentation and followed by re-blurring. Defocus magnification is also as-sociated with depth estimation. ...
