1. A method for detecting occupancy state in a vehicle having an interior passenger compartment, the method comprising:
using at least one processor to:
analyze data of said interior passenger compartment to yield at least one probability of a current occupancy state of said vehicle;
analyze additional data of said interior passenger compartment to yield predicted probabilities of said occupancy state of said vehicle, wherein each probability of said predicted probabilities relate to the probability of changing said current occupancy state to different occupancy state;
combine said at least one probability of the current occupancy state with said predicted probabilities of said occupancy state to yield an updated probability of an updated occupancy state of said vehicle;
determine said current occupancy state based on said updated probability of an updated occupancy state of said vehicle, wherein the current occupancy state includes determination of a number of passengers in the vehicle; and
generate an output to control one or more devices or applications based on the determined occupancy state.
