近几个月来，伊斯兰国对当地文化遗产地的蓄意破坏受到了世界各地媒体的广泛报道。地球观测数据提供了重要信息来评估此类不可到达区域的损害，如果需要快速响应，则需要自动图像处理技术来加快分析速度。本文展示了基于与灾前和灾后卫星图像相关的纹理信息和亮度值鲁棒差异的提取，将快速鲁棒的变化检测技术应用于敏感区域的初步结果。绘制了一张突出显示可能受损建筑物的地图，这可以帮助专家及时评估感兴趣的文化遗产地的受损程度。叙利亚和伊拉克的两个考古遗址取得了令人鼓舞的结果。
The intentional damage to local Cultural Heritage sites carried out in recent months by the Islamic State have received wide coverage from the media worldwide. Earth Observation data provide important information to assess this damage in such non-accessible areas, and automated image processing techniques will be needed to speed up the analysis if a fast response is desired. This paper shows the first results of applying fast and robust change detection techniques to sensitive areas, based on the extraction of textural information and robust differences of brightness values related to pre- and post-disaster satellite images. A map highlighting potentially damaged buildings is derived, which could help experts at timely assessing the damages to the Cultural Heritage sites of interest. Encouraging results are obtained for two archaeological sites in Syria and Iraq.
