Post-earthquake road debris detection based on SEA-Unet using post-event Very High-resolution Remote Sensing Imagery: Case studies in Osmaniye, Türkiye and Sarpol-e Zahab, Iran. Submitted to Big Earth Data journal
Natural disasters, such as earthquakes, cause significant damage to the infrastructure and transportation systems of the affected areas. Rapid and accurate identification of road debris is imperative for practical post-disaster response efforts. Traditional methodologies involving field surveys and visual inspections are time-intensive and may hinder fast response. Leveraging recent developments in remote sensing (RS) technology and deep learning (DL), this study introduces a novel DL-based method, SEA-Unet, for automating road debris detection using Very High-Resolution (VHR) RS imagery. The SEA-Unet framework integrates the Squeezed and Excitation attention (SEA) mechanism and dense skip connections to improve accuracy and efficiency in debris detection. SE attention enables DL models to focus on critical features, substantially enhancing debris detection precision. We validate the proposed SEA-Unet methodology using VHR satellite imagery from the 2023 Osmaniye, Türkiye earthquake (magnitude 7.8, Pleiades acquisition on February 6, 2023) and the 2017 Sarpol-e Zahab, Kermanshah, Iran earthquake (magnitude 7.3 Mw, captured by Phantom 4 Pro). Comparative analysis demonstrated superior performance of SEA-Unet (mIoU=92.68%, Recall=88.39%, Accuracy=97.54% for Osmaniye, Türkiye, and mIoU=93.78%, Recall=89.23%, Accuracy=98.45% for Sarpol-e Zahab, Iran) over well- known models like Unet, ResUnet++, DeepLabV3+, Segnet, and ResUnet. This study shows the efficacy of SE attention in augmenting CNN models for high-precision image analysis, offering a significant advancement in post-disaster debris detection and response capabilities.

Improving the YOLOv5 Deep Neural Network for Detecting Vehicles and Outdoor Pools from Drone Data. Journal of Geomatics and Technology
Abstract : Detecting small objects such as vehicles and swimming pools in high-spatial-resolution drone images is challenging due to their similar geometric and color features. The increase in the number of vehicles is not only a major challenge from the perspective of urban traffic but also leads to environmental problems such as pollution and warming. Therefore, monitoring these targets can play an important role in managing these problems. On the other hand, the construction and maintenance of swimming pools also require a significant amount of water, and monitoring these targets in urban environments is essential for water conservation. In this regard, drone remote sensing images and deep learning networks, which have a high ability to detect objects from these images, are considered suitable tools for monitoring these targets. Although valuable research has been done in this area to address each of the environmental challenges mentioned, there are still shortcomings in them. In this study, a new deep learning network YOLOv5+ has been developed to simultaneously detect two targets, vehicles and swimming pools, from drone images, in which the network's performance in extracting efficient features has been enhanced due to the use of the Inception mechanism in the intermediate layers. Additionally, in this study, DJI Mavic and DJI Mini Se drone data from Tianjin regions in China and the city of Cannes in France were used to evaluate the performance of the proposed network and compare it with the YOLOv5 and YOLOv7 deep learning networks. Finally, the results showed that the proposed network achieved an overall accuracy of 95% on the test set, which is an improvement of 2% over the YOLOv5 and YOLOv7 networks, indicating the efficiency of the approach proposed in this study.
