In these modern times there are still a lot of juvenile delinquencies in the midst of society, especially in urban areas society. Juvenile delinquency may be fighting, illegal racing, gambling, and drawing graffiti on the walls without permission. Graffiti actions on walls are usually done on office building walls and on public or private property. Results from graffiti on the walls can be seen from the changes between the initial image and the image after a motion. This research develops an image change detection system in video to detect the action of graffiti drawing on the wall via a Closed-Circuit Television camera (CCTV) which is done by simulation using the webcam camera. Motion detection process was done with Accumulative Differences Images (ADI) method and image change detection process was done with Illumination Invariant Change Detection method coupled with image cropping method which carried out a comparison between a reference image or image before any movement with the image after a movement. Detection system testing was done in different time variations, i.e. in the morning, noon, afternoon, and evening. The proposed method for image change detection in video give results with an accuracy rate of 92.86%.
