Change Detection Algorithms

Change detection algorithms are tools used to identify differences or shifts in data over time, especially in images or sensor data. They analyze sequential data sets to pinpoint areas where significant changes occur, such as new objects appearing, existing objects disappearing, or alterations in the environment. These algorithms are vital in applications like monitoring forests for deforestation, tracking urban growth, or detecting structural damage. They compare current data to previous versions, filtering out normal variations, to accurately highlight meaningful changes, enabling timely decision-making and responses.
