Learning Visual Motion Segmentation Using Event Surfaces

Anton Mitrokhin, Zhiyuan Hua, Cornelia Fermuller, Yiannis Aloimonos
2020 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)  
The difficulty of the task stems from the fact that unlike in metric space, the shape of an object in (x, y, t) space depends on its motion and is not the same across the dataset.  ...  We evaluate our method on the state of the art event-based motion segmentation dataset -EV-IMO and perform comparisons to a frame-based method proposed by its authors.  ...  Since pixel motion is constrained by the laws of physics, the rigidity of bodies and the epipolar geometry, event clouds are significantly different from 3D point clouds in (x, y, z) space.  ...
