From Motion Blur to Motion Flow: a Deep Learning Solution for Removing Heterogeneous Motion Blur
[article]
2016

Removing pixel-wise heterogeneous motion blur is challenging due to the ill-posed nature of the problem. ...
Our approach directly estimates the motion flow from the blurred image through a fully-convolutional deep neural network (FCN) and recovers the unblurred image from the estimated motion flow. ...
To handle general heterogeneous motion blur, based on the motion flow model, we propose a deep neural network based method able to directly estimate a pixel-wise motion flow map from a single blurred image ...
