Abstract
Methods and systems for motion detection include performing a first prediction to predict voxel occupancy based on a sequence of input point clouds including a current point cloud and a set of previous point clouds. A second prediction is performed to predict voxel occupancy for the sequence of input point clouds using predicted voxel occupancy between the input point clouds. Motion detection is performed based on the completed voxel occupancy. An action is performed responsive to a detected motion.
