Abstract
In this work, we propose a novel framework for unsupervised learning for event cameras that learns to predict optical flow from only the event stream. In particular, we propose an input representation of the events in the form of a discretized 3D volume, which we pass through a neural network to predict the optical flow for each event. This optical flow is used to attempt to remove any motion blur in the event image. We then propose a loss function applied to the motion compensated event image that measures the motion blur in this image. We evaluate this network on the Multi Vehicle Stereo Event Camera dataset (MVSEC), along with qualitative results from a variety of different scenes.
