US 2023/0396741 A1 · COMPUTER-IMPLEMENTED METHOD, COMPUTER PROGRAM AND APPARATUS FOR VIDEO PROCESSING AND FOR GENERATING A THUMBNAIL FROM A VIDEO SEQUENCE, AND VIDEO SURVEILLANCE SYSTEM COMPRISING SUCH AN APPARATUS

Abstract

A computer-implemented method of video processing is provided. The method comprises obtaining a first video sequence of a target area comprising a first predetermined object or activity of interest and obtaining a second video sequence of the target area comprising a second predetermined object or activity of interest. The method further comprises determining whether a recording period of the first video sequence and a recording period of the second video sequence overlap for a time period; and in a case where the recording periods of the first and second video sequences overlap for a time period, defining at least one first video clip using frames of the first and/or second video sequence(s) from at least the time period of overlap.
