Frame Differencing

Frame differencing is a technique used in image and video processing to identify changes between consecutive frames. By comparing each frame to the previous one, it highlights differences, such as movement or new objects appearing. For example, in surveillance systems, frame differencing can detect if a person enters a room by comparing the current image with the last one. This method helps in various applications, including security monitoring, motion detection, and even in video editing, making it easier to track changes over time without needing complex analysis.
