1. A system comprising:
one or more processors; and
one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
receiving, from a temporal sensor of a vehicle and during a first time period, first sensor data including a representation of an object in an environment in which the vehicle is operating, wherein a movement of at least one of the object or the vehicle contributes to a distortion in the representation of the object relative to an actual shape of the object;
determining, based at least in part on the first sensor data, that the object corresponds with a tracked object, the tracked object associated with an estimated size determined based at least in part on second sensor data captured during a second time period, prior to the first time period;
determining a difference between the estimated size and a detected size associated with the representation of the object in the first sensor data;
determining at least one of a velocity or a bounding box associated with the object based at least in part on the difference between the detected size and the estimated size; and
controlling operation of the vehicle based at least in part on the at least one of the velocity or the bounding box.
