Methods and Systems for Background Subtraction Re-Initialization

Example methods and systems for background subtraction re-initialization are disclosed. In an example method, computing system may use a set of active sensors to determine a background representation of a space that can be divided into subspaces with each subspace depicted by a quantity of data points that depends on the active sensors. The system may determine locations of objects moving the space using the active sensors and the background representation. In some instances, the system may receive an indication of a change in the active sensors and responsively determine new quantities of data points that depict each subspace after the change. The system may further adjust 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 active sensors.
