Abstract
Disclosed are systems and methods for tracking and re-identification of agents through sparce and disparate event areas (entry, exit, inventory locations, etc.) within a materials handling facility that includes untracked areas. With the disclosed implementations, only certain areas of a materials handling facility need cameras while other areas may be devoid of cameras. With the disclosed implementations, re-identification of an agent may only occur when the agent enters an authentication event area, such as an exit event area and/or performs a defined action, such as an item pick from an inventory location or an item place to an inventory location. In other instances, while an agent may be tracked while the agent is located within an event area, the tracklet generated for that agent while in that event area may remain unlinked or otherwise disconnected from any other tracklet until re-identification of the agent is performed (e.g., when the agent exits the materials handling facility).
