Abstract

IN A NUCLEAR PLANT, THE AREAS IN WHICH FISSILE MATERIALS ARE STORED OR HANDLED, HAVE TO BE MONITORED CONTINUOUSLY. ONE METHOD OF SURVEILLANCE IS TO RECORD PICTURES WITH TV CAMERAS WITH DETERMINED TIME INTERVALS ON SPECIAL VIDEO RECORDERS. THE "TIME LAPSE" RECORDED TAPE IS PLAYED BACK AT NORMAL SPEED AND AN INSPECTOR CHECKS VISUALLY THE PICTURES. THE REPORT DESCRIBES AN AUTOMATIC REVIEWING METHOD BASED ON AN IMAGE PROCESSING SYSTEM. THE SYSTEM DETECTS SCENE CHANGES IN THE PICTURE SEQUENCE AND STORES THE REDUCED DATA SET ON A SEPARATE VIDEO TAPE. THE RESULTING REDUCTION OF REVIEWING TIME BY INSPECTOR IS IMPORTANT FOR SURVEILLANCE DATA WITH FEW MOVEMENTS.
