1. A method for detecting abnormal passenger behavior in a vehicle, the method comprising:
receiving, with a processing system, a first image frame of at least one passenger in a cabin of the vehicle from an image sensor;
determining, with the processing system, based on the first image frame, a first numerical vector representing a pose and a motion of the at least one passenger in the first image frame, the determining the first numerical vector including determining, with the processing system, a respective plurality of key points for each of the at least one passenger, each key point including a coordinate pair corresponding to a position of a respective joint or body part of the at least one passenger within the first image frame; and
detecting, with the processing system, based on the first numerical vector, abnormal passenger behavior in the first image frame using a mixture model having a plurality of cluster components representing normal passenger behaviors.
