Change Detection For Remote Sensing Images

Change detection in remote sensing images refers to the technology of identifying and quantifying changes in land features by comparing images of the same area acquired at different time points. Its objective is to accurately extract change information to support decision-making. This technology has significant application value in urban planning, environmental monitoring, disaster assessment, and other fields, effectively assisting in resource management and emergency response. Methodologically, it typically involves steps such as image preprocessing, feature extraction, change detection, and post-processing.
