Abstract
Image change detection is an active research topic in the field of remote sensing, as it allows monitoring environmental changes that occur on temporal and spatial scales. However, most of the existing change detection methods suffer from a lack of adaptability to different image types and lack of large-scale validation. In this study, we propose an automatic change detection method, called "CD-ResUNet," based on multi-spectral NDVI imagery. It is an end-to-end deep learning method based on the fusion of two complementary deep learning networks: UNet and residual networks (ResNet). Extensive experiments have been conducted on low-resolution as well as high-resolution datasets using four represented geographical areas, which are Colombia, California, Brazil, and Duluth, each containing 145,161 patches, and the Change Detection Dataset containing 16,000 patches. For all the investigated regions, the proposed method outperforms many relevant state-of-the-art methods with an accuracy up to 99.5% and an F1-score of 99.40%.
