Method and system for video-based vehicle tracking adaptable to traffic conditions

摘要

A method and system for adaptable video-based object tracking includes acquiring video data from a scene of interest and identifying an initial instance of an object of interest in the acquired video data. A representation of a target object is then established. One or more motion parameters associated with said scene of interest are used to adjust the size of a search neighborhood associated with said target object. The target object is then tracked frame-by-frame in the video data.

1. A method for video-based object tracking, said method comprising:
selecting at least one motion parameter from a plurality of motion parameters associated with a scene of interest; defining a motion environment state according to said selected at least one motion parameter, wherein said selected at least one motion parameter is indicative of a pattern of motion in said scene of interest; setting a size of a search neighborhood associated with a target object according to said motion environment state; adjusting said motion environment state as said pattern of motion in said scene of interest changes; adjusting said size of said search neighborhood associated with said target object in response to said adjusted motion environment state; and determining a frame-by-frame location of said target object using said adjusted search neighborhood size in order to track said target object in said video data.
