A score having a predefined value is established for the traffic signal candidate. The traffic signal candidate is tracked by incrementing the score when the traffic signal candidate is determined to appear, based on a probabilistic estimator that indicates an expected value for a location of the traffic signal candidate, in a tracked image frame of the captured image frames. The score is decremented when the traffic signal candidate is determined not to appear, based on the probabilistic estimator, in the tracked image frame. The traffic signal candidate is recognized as a traffic signal based on whether the score is above a specified threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for traffic signal recognition","description":"Detecting traffic signaling of a mobile environment includes receiving image frames captured by an imaging device to detect a traffic signal candidate therefrom based on at least a vehicle location.
