Scene change detection method for monitoring system

Abstract

A method of scene change detection applicable to a monitoring system having an image capture module is disclosed. The method includes the steps of: capturing a first image and a second image containing the same target by an image capture module at different timestamps; respectively transforming the first and the second images into a first semantic segmentation mask and a second semantic segmentation mask using a pre-trained semantic segmentation model; comparing class values of a first resultant map and a second resultant map respectively derived from the first and the second semantic segmentation masks on a pixel-by-pixel basis to count a number P1 of pixel positions with different class values; and triggering one or more actions by the monitoring system according to the number P1 and a total number of pixels in the first and the second resultant maps.
