    • A system for improving limited sensor estimates using rich sensor estimates is described. The system includes one or more computers and one or more storage devices storing instructions that, when executed by one or more computers, cause the one or more computers to perform operations including: performing the following steps at least once: receiving rich sensor data, captured by a high-resolution sensor, of an input scene; receiving limited sensor data, captured by a low-resolution sensor, of the input scene; processing the rich sensor data using a first estimator to generate a first estimate that represents a first set of characteristics of the input scene; processing the limited sensor data using a second estimator to generate a second estimate in accordance with current values of parameters of the second estimator, the second estimate representing a second set of characteristics of the input scene, the second estimator being a deep neural network; determining a loss function that represents a difference in quality between the first estimate and the second estimate; and training the second estimator by adjusting the current values of the parameters of the second estimator to minimize the loss function. The operations further include: obtaining new limited sensor data, captured by the low-resolution sensor, of a new input scene; and processing the new limited sensor data using the trained second estimator in accordance with the adjusted values of parameters of the second estimator to generate a new estimate that represents a new set of characteristics of the new input scene.
