Millions of buried and surface landmines throughout the world will continue to kill and injure people for many decades. Reliable landmine detection systems, especially those that do not require that an operator enters a minefield, are demanded. In such systems, data are captured by sensors and processed with signal-processing techniques. In recent studies, ground-penetrating radars, ultrasound transducers, metal detectors, and infrared sensors have been used to capture data as individual images or image time series. Bare soil and mines have different thermal characteristics, and this difference can be observed on the soil surface with thermal sensors. Since this is a dynamic behavior driven by radiation from the sun and changes with temperature during the day, it can be observed better in thermal image time series. In the proposed method, a two-step approach is adopted: pixelwise classification followed by mine detection. In the first step, a specific spatial filter is applied on images and the filtered image series is classified pixelwise using supervised classification. In the second step, the classified pixels are combined after a smoothing operation to detect mines. The types of the detected mines can also be determined. The method is tested on real data to quantify its classification and detection performance. The results are quite promising. Among the classifiers tested in this paper, the quadratic discriminate function classifier produces the best results.

Buried and surface mine detection from thermal image time series Kaya, Serkan; Leloğlu, Uğur Murat; Department of Geodetic and Geographical Information Technologies (2016) Since many countries suffer from existence of landmines in their territory, there is a growing demand for reliable landmine detection systems. Most of these systems require an operator to enter into the minefield. However, infrared sensor methods can be used remotely; hence, they do not put lives at risk during the search operation. In this thesis, a new approach to the infrared sensor method, which gives promising results, is presented.Buried landmines generate specific spatiotemporal thermal image pattern...
Buried wire detection using ground penetrating radars Yılmaz, Utku; Akar, Gözde; Department of Electrical and Electronics Engineering (2017) Buried explosives pose great threat for national security of the countries struggling with these explosives as the damage caused by them increase day by day. There are several sensors developed for detection of buried explosives such as land mines, unexploded ordnances and improvised explosive devices (IEDs). Among these, IEDs are quite hard to detect with majority of sensors due to their irregular shape and contents. The difficulties in IED detection have led researchers to aim the triggering mechanisms of...
Pre-Positioning of Emergency Items for CARE International Duran, Serhan; Keskinocak, Pinar (2011-05-01) Each year, about 500 natural disasters kill approximately 70,000 people and affect more than 200 million people worldwide. In the aftermath of such events, large quantities of supplies are needed to provide relief aid to the affected. CARE International is one of the largest humanitarian organizations that provide relief aid to disaster survivors. The most vital issues in disaster response are agility in mobilizing supplies and effectiveness in distributing them. To improve disaster response, a research gro...
Pre-Positioning Disaster Response Facilities and Relief Items RENKLİ, Cigdem; Duran, Serhan (2015-07-04) Large-scale disasters cause enormous damage to people living in the affected areas. Providing relief quickly to the affected is a critical issue in recovering the effects of a disaster. Pre-disaster planning has an important role on reducing the arrival time of relief items to the affected areas and efficiently allocating them. In this study, a mixed integer programming model is proposed in order to pre-position warehouses throughout a potential affected area and determine the amount of relief items to be h...
Satellite Remote Sensing and Hydrologic Modeling for Flood Inundation Mapping in Lake Victoria Basin: Implications for Hydrologic Prediction in Ungauged Basins Khan, Sadiq I.; Hong, Yang; Wang, Jiahu; Yılmaz, Koray Kamil; Gourley, Jonathan J.; Adler, Robert F.; Brakenridge, G. Robert; Policelli, Fritz; Habib, Shahid; Irwin, Daniel (2011-01-01) Floods are among the most catastrophic natural disasters around the globe impacting human lives and infrastructure. Implementation of a flood prediction system can potentially help mitigate flood-induced hazards. Such a system typically requires implementation and calibration of a hydrologic model using in situ observations (i.e., rain and stream gauges). Recently, satellite remote sensing data have emerged as a viable alternative or supplement to in situ observations due to their availability over vast ung...
