Morphological Change Detection in Terror Camps of Area 1 and 2 by Pre- and Post-strike Through MOAB: A

摘要

Change Detection (CD) techniques have emerged out as an effective tool to monitor various positives and negatives aspects of any event, whether these events are related to the development or destruction of human civilization. These techniques provide us binary (Yes-No) and detailed information about various types of statistical changes that get developed in the land cover after any event. In this context, MOAB (Mother of All Bomb) strike on Islamic State militants in Achin, District of Nangarhar province, Afghanistan can be referred as a step taken to establish peace and stability in that disturbed region. Here, the morphological changing conditions are analysed by the texture based post classification CD technique by comparing the second-order statistics of pre-strike and post-strike images of Area 1 and Area 2. A novel technique to compute circular texture varying from 0° to 360° is fused with Decorrelation Stretcher (DS) technique. The possible hideouts of the terrorist before the strike and demolished structures after strike are highlighted by colour processing in Red, Green, and Blue (RGB) band forms. Quantification of the texture features along with visual interpretation through DS establishes a pattern in the changing texture features of the land cover in the affected areas.
