A repeater is any output module that stores all received localizations in memory and can repeat them if necessary. While this costs, naturally, roughly 32 bytes of memory per localization, it allows changing many processing parameters even after computation has started.

However, repeaters are not able to store the input images used in computation because doing so would quickly exhaust the available memory. Therefore, output modules that need access to source images may not be used as children of repeater modules.
