Abstract: A computer that includes a processor and a memory, the memory including instructions executable by the processor to plot three-dimensional positions of labeled cuboids from successive frames between a first keyframe and a second keyframe of a densely labeled video sequence. A sparsely labeled video sequence can be generated by removing labeled cuboids from the densely labeled video sequence with positions that are within a user-selected distance from a line extending from a position of the labeled cuboid in the first keyframe to a position of the labeled cuboid in the second keyframe. The sparsely labeled video sequence can be output for training a machine learning system.

Abstract: A vehicle computer can access a stored map. The map includes respective vehicle operating permissions for zones included in the map. A changed vehicle operating permission for one of the zones included in the map may be received. When the vehicle is within a specified distance of the one of the zones, the vehicle is operated according to the changed operating permission. The changed vehicle operating permission can downgrade autonomous control of vehicle speed and/or steering.
