Landslide Detection with Unmanned Aerial Vehicles
2021 International Conference on Multimedia Analysis and Pattern Recognition (MAPR), 2021 Landslide is one of the most dangerous disasters, especially for countries with large mountainous terrain. It causes a great damage to lives, infrastructure and environments, such as traffic congestion and high accidents. Therefore, automated landslide detection is an important task for warning and reducing its consequences such as blocked traffic or ...
