Claim One:
1. A method comprising: determining, at a computing system using a set of active sensors, a background representation of a space, wherein the background representation is divided into a plurality of subspaces, and wherein each subspace is depicted by a quantity of data points in the background representation that depends on the set of active sensors; for one or more subspaces of the space, detecting a change in a quantity of data points depicting a corresponding subspace above a threshold change in quantity of data points; determining, at the computing system using the set of active sensors and the background representation of the space, locations of objects moving in the space based on detected changes in quantities of data points depicting corresponding subspaces above the threshold change in quantity of data points; receiving an indication of a change in the set of active sensors; responsive to receiving the indication, determining new quantities of data points that depict each subspace of the space after the change in the set of active sensors; and adjusting, at the computing system, the background representation of the space by subtracting data points corresponding to the determined locations of the objects moving in the space from the new quantities of data points that depict each subspace of the space after the change in the set of active sensors.
