METHOD FOR DETECTING ABANDONED OBJECT AND REMOVED OBJECT IN VIDEO STREAM, AND COMPUTER PROGRAM, AND COMPUTER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for processing a time-ordered sequence of video frames.

SOLUTION: The method is implemented by execution of program code on a processor of a computer system. Each frame includes a two-dimensional array of pixels and a frame-dependent color intensity at each pixel. A current frame and at least one frame occurring prior to the current frame in the sequence are analyzed by a background subtraction on the at least one frame to determine a background image and a static region mask associated with a static region. The background subtraction determines an existence of a static object relating to the static region. A status of the static object is determined. The status may be either that the static object is an abandoned object or that the static object is a removed object. The determined status is stored in a data storage medium of the computer system.
